Abstract
Description
Technical Field
[0001] This utility model relates to the field of dishwashers, and in particular to a spray device and a dishwasher. Background Technology
[0002] Traditional dishwashers primarily use electric motors to power the spray system. Using an electric motor requires very high protection and insulation levels, and imposes strict requirements on the motor's lifespan and torque. Achieving these requirements inevitably leads to a complex product structure and higher costs. Furthermore, an electric motor-driven spray system can only rotate 360 degrees, causing it to spray unnecessary areas within the dishwasher, resulting in unnecessary waste of washing water and low spray efficiency. Utility Model Content
[0003] Therefore, it is necessary to address the problem that traditional dishwashers use a spray device that sprays water onto parts of the dishwasher that do not need to be sprayed, resulting in unnecessary waste of washing water and low spray efficiency. A spray device and a dishwasher should be provided.
[0004] A spraying device includes: a power source assembly having an inlet and an outlet, and a power chamber, wherein the inlet, the power chamber, and the outlet are sequentially connected; a spraying assembly disposed on the power source assembly and connected to the outlet; a rotating member disposed on the power source assembly, wherein the power source assembly can drive the rotating member to rotate when liquid is input into the power chamber; a rocker arm disposed on the spraying assembly; and a connecting member connected to the rotating member and the rocker arm respectively; wherein the rotating member can drive the spraying assembly to rotate relative to the power source assembly in a first direction and a second direction, the second direction being opposite to the first direction.
[0005] The first aspect of this application discloses a spraying device in which a power source component drives a rotating part when washing water is introduced through a power chamber, providing power for the rotation of the rotating part. This design replaces the traditional motor drive, eliminating the need to consider motor design factors and reducing production costs. The water outlet is connected to the power chamber, and the spraying component is connected to the water outlet, allowing the washing water providing kinetic energy to be delivered to the spraying component for spraying, preventing waste of washing water. A crank-connecting rod-rocker structure, with the rotating part, connecting part, and rocker arm connected in sequence, ensures that the spraying component can only rotate reciprocally within a certain area, replacing the 360-degree rotation of traditional spraying components. This prevents unnecessary waste of washing water by spraying areas inside the dishwasher that do not require spraying. This design effectively improves the spraying efficiency of the spraying device. For example, some auxiliary spraying components only need to clean specific areas of the dish rack or tray; this design allows them to focus on spraying specific areas without spraying the side walls or bottom walls of the inner drum, resulting in high spraying efficiency and avoiding water waste.
[0006] In one embodiment, the rotating component's movement trajectory is circular. Because the rotating component's movement trajectory is circular, it can rotate in one direction and 360 degrees, causing the connecting component to drive the spray assembly to reciprocate, thus improving spray efficiency.
[0007] In one embodiment, the connector has an arc-shaped cross-section. This arc-shaped cross-section better conforms to the relative motion trajectory between the rotating component and the rocker arm, allowing for better adaptation to angular changes during the reciprocating oscillation of the spray assembly and improving the overall mechanism's coordination. This design ensures smoother and more stable reciprocating rotation of the spray assembly, resulting in higher spraying efficiency.
[0008] In one embodiment, one end of the connector is movably connected to the rotating member, and the other end of the connector is movably connected to the rocker arm. The sequential movable connection of the rotating member, connector, and rocker arm ensures smoother conversion of the continuous rotational motion of the rotating member into the reciprocating rotation of the spray assembly. The design, with the rotating member and rocker arm connected to both ends of the connector respectively, is more rational, resulting in more efficient power transmission and significantly improved spraying efficiency.
[0009] In one embodiment, one end of the rotating component is drive-connected to the power source assembly, and the other end of the rotating component is movably connected to the connecting component. By connecting both ends of the rotating component to the power source assembly and the connecting component respectively, the design is more rational and can effectively improve power transmission efficiency, thereby improving spraying efficiency.
[0010] In one embodiment, the spray assembly includes a liquid delivery channel and multiple spray holes arranged sequentially along the length of the spray assembly. The water outlet, the liquid delivery channel, and the multiple spray holes are sequentially connected. By arranging multiple spray holes sequentially along the length of the spray assembly, for example, multiple spray holes on the same straight line, instead of the traditional dispersed, circumferential arrangement of spray holes, waste of washing water caused by outputting washing water in unnecessary directions can be avoided. This design avoids dispersing unnecessary hydraulic pressure and improves spray efficiency.
[0011] In one embodiment, the water outlet is located at the bottom of the power source assembly. Positioning the water outlet at the bottom of the power source assembly helps prevent the accumulation of washing water.
[0012] In one embodiment, the rotating member is provided with an adapter hole that can mate with the power source assembly.
[0013] In one embodiment, the rotating member includes a rotating part and an assembly part, the rotating part being connected to the power source assembly, and the assembly part being disposed on the rotating part for cooperating with the connecting member.
[0014] In one embodiment, the spray assembly rotates at an angle of less than 180 degrees. The rotation angle of the spray assembly is also theoretically less than 180 degrees, as is the rotation angle of the rocker arm. This design allows the spray assembly to rotate only within a certain area, replacing the 360-degree rotation of traditional spray assemblies, and preventing unnecessary waste of washing water by spraying areas inside the dishwasher that do not require spraying.
[0015] In one embodiment, the connector is provided with multiple first adjustment holes, each capable of engaging with the rotating component. By allowing multiple first adjustment holes to engage with the rotating component, the rotating component can be matched with a selected first adjustment hole as needed. This design ensures that even if one first adjustment hole fails, other first adjustment holes can be used without replacing the connector, effectively extending the product's lifespan.
[0016] In one embodiment, a plurality of first adjustment holes are sequentially arranged along the extension direction of the connector. By sequentially arranging a plurality of first adjustment holes along the extension direction of the connector, the spray assembly can rotate at different angles when the rotating member is engaged in different first adjustment holes, thereby increasing or decreasing the spray area of the spray assembly accordingly, making it suitable for more different tableware placement methods.
[0017] In one embodiment, when one of the plurality of first adjustment holes engages with the rotating member, the maximum angle at which the spray assembly can rotate is β1, and when the other of the plurality of first adjustment holes engages with the rotating member, the maximum angle at which the spray assembly can rotate is β2, wherein β2 is greater than β1. By allowing the spray assembly to rotate at different angles when the rotating member engages with different first adjustment holes, the spray area of the spray assembly can be increased or decreased accordingly, making it suitable for more different tableware placement methods. It can also focus on spraying heavily soiled areas, improving tableware cleaning efficiency.
[0018] In one embodiment, the end of the rocker arm furthest from the spray assembly is movably connected to the connector. This movable connection between the end of the rocker arm furthest from the spray assembly and the connector is a more rational design, resulting in smoother power transmission between the connector and the rocker arm, improving the reciprocating rotation efficiency of the spray assembly, and thus enhancing the spraying efficiency of the spray assembly.
[0019] In one embodiment, the rocker arm extends radially along the spray assembly. This radial extension of the rocker arm allows for better power transmission by sequentially connecting the rotating member, the connecting member, and the rocker arm to drive the spray assembly to reciprocate, thereby improving spray efficiency.
[0020] In one embodiment, the connector is provided with multiple second adjustment holes. These holes are arranged sequentially or spaced apart along the extension direction of the connector. Each second adjustment hole can engage with the rocker arm. When one of the second adjustment holes engages with the rocker arm, the maximum rotation angle of the spray assembly is β3. When another of the second adjustment holes engages with the rocker arm, the maximum rotation angle of the spray assembly is β4, where β4 is greater than β3. By varying the rotation angle range of the spray assembly when the rocker arm engages with different second adjustment holes, the spray area of the spray assembly can be increased or decreased accordingly. This makes it suitable for more diverse tableware arrangement methods and allows for targeted spraying of heavily soiled areas, improving tableware cleaning efficiency.
[0021] In one embodiment, the power source assembly includes a housing, a drive assembly, and a transmission assembly. The housing has a water inlet, a power chamber, and a water outlet. The housing also has a transmission chamber. The drive assembly is mounted on the housing and located within the power chamber. The transmission assembly is mounted on the housing and located within the transmission chamber. The transmission assembly is drively connected to the drive assembly and to the rotating component. When liquid enters the power chamber, the drive assembly drives the transmission assembly, ultimately driving the rotating component to rotate. This design utilizes the washing water that would otherwise be sprayed as power to provide kinetic energy to the drive assembly. This design replaces traditional motor drives, eliminating the need to consider motor design factors, and making the control method simpler, more convenient, and more environmentally friendly. By placing the drive assembly within the power chamber and the transmission assembly within the transmission chamber, and separating the power chamber and transmission chamber, it helps prevent food residue and other contaminants from entering the transmission chamber and becoming difficult to clean, thus preventing the growth of viruses and bacteria.
[0022] In one embodiment, the housing includes a first shell and a second shell. The first shell has the water inlet, the power chamber, and the water outlet. The second shell is disposed on the first shell, and the second shell and the first shell together form the transmission chamber. By having the power chamber in the first shell and the transmission chamber formed by the second shell and the first shell being separate, the power chamber and the transmission chamber are effectively separated, which helps prevent food residue and other contaminants from entering the transmission chamber and becoming difficult to clean, thus preventing the growth of viruses and bacteria.
[0023] In one embodiment, the drive assembly includes a drive impeller and a drive rod. The drive impeller is mounted on the housing and located within the power chamber. The housing has a through-hole, and the drive rod is mounted on the drive impeller, passing through the through-hole and connecting to the transmission assembly. The housing has a water inlet channel, and the water inlet, the water inlet channel, and the power chamber are sequentially connected. The extension direction of the water inlet channel is tangent to the outer circle of the drive impeller. The housing also has a water outlet channel, and the power chamber, the water outlet channel, and the water outlet are sequentially connected. The extension direction of the water outlet channel is tangent to the outer circle of the drive impeller. Because the extension directions of the water inlet and outlet channels are tangent to the outer circle of the drive impeller, liquid enters from the tangential direction of the drive impeller, enabling more effective driving of the impeller. The transmission assembly connects to the drive rod, so that the rotation of the impeller drives the rotation of the transmission assembly. This design replaces the traditional motor drive method, making the control simpler, more convenient, and lower in cost.
[0024] In one embodiment, the transmission assembly includes an input gear, a first support shaft, a second support shaft, and a transmission gear. The input gear is driveably connected to the drive assembly. Both the first and second support shafts are mounted on the housing and located within the transmission cavity. Either the first or second support shaft is driveably connected to the rotating component. The transmission gear is mounted on either the first or second support shaft. By using the input gear, the transmission gear, and one of the first or second support shafts as an output shaft and drively connecting to the rotating component, efficient power transmission can be achieved, enabling the rotating component to rotate reliably and stably under the drive of the transmission assembly.
[0025] In one embodiment, the transmission gear includes a first gear mounted on the first support shaft. The first gear meshes with the input gear, and the diameter of the first gear is larger than the diameter of the input gear. The first support shaft is connected to the rotating component in a transmission connection. By having the first gear mesh with the input gear and having a larger diameter than the input gear, speed reduction is achieved, resulting in more stable and reliable rotation of the rotating component.
[0026] In one embodiment, the transmission gear includes a second gear, a third gear, and a fourth gear. The second and third gears are both mounted on the first support shaft, and the diameter of the second gear is larger than that of the third gear. The second gear meshes with the input gear, and its diameter is also larger than that of the input gear. The fourth gear is mounted on the second support shaft, meshes with the third gear, and its diameter is also larger than that of the third gear. The second support shaft is connected to the rotating component via a transmission connection. The arrangement of the second, third, and fourth gears achieves multi-stage speed reduction, resulting in more stable and reliable rotation of the rotating component.
[0027] In one embodiment, the transmission gears include a fifth gear, a sixth gear, a seventh gear, an eighth gear, and a ninth gear. The fifth and sixth gears are both mounted on the first support shaft, and the diameter of the fifth gear is larger than that of the sixth gear. The fifth gear meshes with the input gear, and its diameter is also larger than that of the input gear. The seventh and eighth gears are both mounted on the second support shaft, and the diameter of the seventh gear is larger than that of the eighth gear. The seventh gear meshes with the sixth gear, and its diameter is also larger than that of the sixth gear. The ninth gear is mounted on the first support shaft, meshes with the eighth gear, and its diameter is also larger than that of the eighth gear. The first support shaft is connected to the rotating component via a transmission connection. The arrangement of the fifth, sixth, seventh, eighth, and ninth gears achieves multi-stage speed reduction, resulting in more stable and reliable rotation of the rotating component.
[0028] A dishwasher includes: an inner tub assembly; a dish rack assembly disposed on the inner tub assembly; and the aforementioned spray device disposed on the inner tub assembly and / or the dish rack assembly.
[0029] The second aspect of this application discloses a dishwasher that utilizes the reciprocating rotation of the spray assembly to focus cleaning on specific areas within the dish rack assembly, such as areas with densely packed or heavily soiled dishes. This avoids the ineffective spraying of non-target areas, such as the inner drum wall, by traditional spray structures, significantly improving cleaning efficiency and effectively reducing water waste. Furthermore, the separate design of the power chamber and transmission chamber helps prevent food residue and other contaminants from entering the transmission chamber and becoming difficult to clean, thus preventing the growth of viruses and bacteria.

[0056] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0057] Example 1
[0058] like Figure 1 and Figure 3-5 As shown, this embodiment discloses a spraying device, including: a power source assembly 1, which has an inlet 101 and an outlet 103, and a power chamber 102, wherein the inlet 101, the power chamber 102, and the outlet 103 are sequentially connected; a spraying assembly 2, which is disposed on the power source assembly 1 and is connected to the outlet 103; a rotating member 3, which is disposed on the power source assembly 1, and the power source assembly 1 can drive the rotating member 3 to rotate when liquid is input into the power chamber 102; a rocker arm 4, which is disposed on the spraying assembly 2; and a connecting member 5, which is connected to the rotating member 3 and the rocker arm 4 respectively; the rotating member 3 can drive the spraying assembly 2 to rotate relative to the power source assembly 1 in a first direction and a second direction, wherein the second direction is opposite to the first direction.
[0059] The first aspect of this application discloses a spraying device in which a power source assembly 1 drives a rotating component 3 via a power chamber 102 when washing water is introduced, providing power for the rotation of the rotating component 3. This design replaces the traditional motor drive, eliminating the need to consider motor design factors and reducing production costs. The water outlet 103 is connected to the power chamber 102, and the spraying assembly 2 is also connected to the water outlet 103. The washing water used to provide kinetic energy can be delivered to the spraying assembly 2 through the water outlet 103 for spraying, preventing waste of washing water. The sequential connection of the rotating component 3, connecting component 5, and rocker arm 4, similar to a crank-connecting rod-rocker arm structure, allows the spraying assembly 2 to rotate only within a certain area, replacing the traditional 360-degree rotation of the spraying assembly 2. This prevents unnecessary waste of washing water by spraying areas inside the dishwasher that do not require spraying. This design effectively improves the spraying efficiency of the spraying device. For example, some auxiliary spray components 2 only need to clean the bowl basket or tray locally. This design allows them to focus on spraying specific areas without spraying the side walls, bottom walls, etc. of the inner liner. This results in high spraying efficiency and avoids water waste.
[0060] In addition to the features of the above embodiments, this embodiment further specifies that the movement trajectory of the rotating member 3 is circular. Because the movement trajectory of the rotating member 3 is circular, the rotating member 3 can rotate in one direction and can rotate 360 degrees, causing the connecting member 5 to drive the spray assembly 2 to reciprocate under the drive of the rotating member 3, thereby improving spraying efficiency.
[0061] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-section of the connecting member 5 is arc-shaped. The arc-shaped cross-section of the connecting member 5 better conforms to the relative motion trajectory between the rotating member 3 and the rocker arm 4, and can better adapt to the angle changes during the reciprocating swing of the spray assembly 2, improving the overall coordination of the mechanism. This design ensures smoother and more stable reciprocating rotation of the spray assembly 2, resulting in high spraying efficiency.
[0062] like Figure 1 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: one end of the connecting member 5 is movably connected to the rotating member 3, and the other end of the connecting member 5 is movably connected to the rocker arm 4. The sequential movable connection of the rotating member 3, the connecting member 5, and the rocker arm 4 ensures a smoother conversion of the continuous rotational motion of the rotating member 3 into the reciprocating rotation of the spray assembly 2. The connection of the rotating member 3 and the rocker arm 4 to both ends of the connecting member 5 is a more rational design, making power transmission more efficient and effectively improving spraying efficiency.
[0063] like Figure 1 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: one end of the rotating member 3 is connected to the power source assembly 1 for transmission, and the other end of the rotating member 3 is movably connected to the connecting member 5. By connecting both ends of the rotating member 3 to the power source assembly 1 and the connecting member 5 respectively, the design is more reasonable and can effectively improve the power transmission efficiency, thereby improving the spraying efficiency.
[0064] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the spray assembly 2 includes a liquid delivery channel 201 and spray holes 202, and the number of spray holes 202 is multiple. These multiple spray holes 202 are sequentially arranged along the length direction of the spray assembly 2, and the water outlet 103, the liquid delivery channel 201, and the multiple spray holes 202 are sequentially connected. By arranging multiple spray holes 202 sequentially along the length direction of the spray assembly 2, for example, multiple spray holes 202 on the same straight line, the traditional dispersed and circumferential arrangement of spray holes 202 is replaced, which avoids the waste of washing water caused by outputting washing water in unnecessary directions. This design avoids dispersing unnecessary hydraulic pressure and can improve spraying efficiency.
[0065] like Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the water outlet 103 is located at the bottom of the power source assembly 1. The location of the water outlet 103 at the bottom of the power source assembly 1 helps prevent the residue of washing water.
[0066] like Figure 2 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the rotating member 3 is provided with an adapter hole 301, and the adapter hole 301 can cooperate with the power source assembly 1.
[0067] like Figure 2 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the rotating member 3 includes a rotating part 31 and an assembly part 32, the rotating part 31 is connected to the power source assembly 1, the assembly part 32 is disposed on the rotating part 31, and the assembly part 32 is used to cooperate with the connecting member 5.
[0068] In addition to the features of the above embodiments, this embodiment further specifies that the rotation angle of the spray assembly 2 is less than 180 degrees. The rotation angle of the spray assembly 2 is less than 180 degrees, and theoretically, the rotation angle of the rocker arm 4 is also less than 180 degrees. This design allows the spray assembly 2 to rotate reciprocally within a certain area, replacing the traditional 360-degree rotation of the spray assembly 2, and preventing unnecessary waste of washing water by spraying areas inside the dishwasher that do not require spraying.
[0069] like Figure 2 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the connector 5 is provided with a first adjustment hole 501, and the number of the first adjustment holes 501 is multiple, all of which can cooperate with the rotating member 3. Since multiple first adjustment holes 501 can cooperate with the rotating member 3, the rotating member 3 can be matched with a selected first adjustment hole 501 as needed. This design ensures that even if one of the first adjustment holes 501 is damaged, other first adjustment holes 501 can be used for matching without replacing the connector 5, effectively extending the product's service life.
[0070] like Figure 2 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a plurality of first adjustment holes 501 are sequentially arranged along the extension direction of the connector 5. By sequentially arranging a plurality of first adjustment holes 501 along the extension direction of the connector 5, the spray assembly 2 can rotate at different angles when the rotating member 3 is engaged in different first adjustment holes 501, thereby increasing or decreasing the spray area of the spray assembly 2 accordingly, making it suitable for more different tableware placement methods.
[0071] In addition to the features of the above embodiments, this embodiment further specifies that: when one of the plurality of first adjustment holes 501 cooperates with the rotating member 3, the maximum angle that the spray assembly 2 can rotate is β1; when the other of the plurality of first adjustment holes 501 cooperates with the rotating member 3, the maximum angle that the spray assembly 2 can rotate is β2, and β2 is greater than β1. By allowing the spray assembly 2 to rotate at different angles when the rotating member 3 cooperates with different first adjustment holes 501, the spraying area of the spray assembly 2 can be increased or decreased accordingly, making it suitable for more different tableware placement methods. It also allows for targeted spraying of heavily soiled areas, improving tableware cleaning efficiency.
[0072] like Figure 1 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the end of the rocker arm 4 away from the spray assembly 2 is movably connected to the connector 5. By movably connecting the end of the rocker arm 4 away from the spray assembly 2 to the connector 5, the design is more reasonable, the power transmission between the connector 5 and the rocker arm 4 is smoother, the reciprocating rotation efficiency of the spray assembly 2 is improved, thereby increasing the spraying efficiency of the spray assembly 2.
[0073] like Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that the rocker arm 4 extends radially along the spray assembly 2. By extending the rocker arm 4 radially along the spray assembly 2, the sequential connection of the rotating member 3, the connecting member 5, and the rocker arm 4 enables better power transmission to drive the spray assembly 2 to reciprocate, thereby improving spraying efficiency.
[0074] In addition to the features of the above embodiments, this embodiment further specifies that: the connecting member 5 is provided with a second adjustment hole, and the number of the second adjustment holes is multiple. The multiple second adjustment holes are arranged sequentially along the extension direction of the connecting member 5 or spaced apart. All of the multiple second adjustment holes can cooperate with the rocker arm 4. When one of the multiple second adjustment holes cooperates with the rocker arm 4, the maximum angle that the spray assembly 2 can rotate is β3, and when the other of the multiple second adjustment holes cooperates with the rocker arm 4, the maximum angle that the spray assembly 2 can rotate is β4, where β4 is greater than β3. Because the range of angles that the spray assembly 2 can rotate varies when the rocker arm 4 cooperates with different second adjustment holes, the spraying area of the spray assembly 2 can be increased or decreased accordingly. This is suitable for more different tableware placement methods and allows for targeted spraying of heavily contaminated areas, improving tableware cleaning efficiency.
[0075] like Figure 11-13 As shown, in addition to the features of the above embodiments, this embodiment further defines the following: the power source assembly 1 includes a housing 11, a drive assembly 12, and a transmission assembly 13. The housing 11 is provided with the water inlet 101, the power chamber 102, and the water outlet 103. The housing 11 is also provided with a transmission chamber 104. The drive assembly 12 is disposed on the housing 11 and located within the power chamber 102. The transmission assembly 13 is disposed on the housing 11 and located within the transmission chamber 104. The transmission assembly 13 is driveably connected to the drive assembly 12 and to the rotating member 3. When liquid is input into the power chamber 102, the drive assembly 12 can drive the transmission assembly 13, ultimately driving the rotating member 3 to rotate. The washing water, which is already being sprayed, can be used as power to provide kinetic energy to the drive assembly 12. This design replaces the traditional motor drive, eliminating the need to consider motor design factors, making the control method simpler, more convenient, and more environmentally friendly. With the drive assembly 12 located in the power chamber 102 and the transmission assembly 13 located in the transmission chamber 104, and the power chamber 102 and the transmission chamber 104 being set separately, it is beneficial to prevent the residues such as vegetable scraps from entering the transmission chamber 104, which are difficult to clean and may generate viruses and bacteria.
[0076] like Figure 9-12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing 11 includes a first housing member 111 and a second housing member 112. The first housing member 111 is provided with the water inlet 101, the power chamber 102, and the water outlet 103. The second housing member 112 is disposed on the first housing member 111, and the second housing member 112 and the first housing member 111 enclose the transmission chamber 104. By providing the power chamber 102 in the first housing member 111 and the second housing member 112 enclosing the transmission chamber 104 in the first housing member 111, the power chamber 102 and the transmission chamber 104 are separated, which helps to prevent food residues and other contaminants from entering the transmission chamber 104 and becoming difficult to clean, thus preventing the generation of viruses and bacteria.
[0077] like Figure 11 and Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further defines: the drive assembly 12 includes a drive impeller 121 and a drive rod 122. The drive impeller 121 is disposed on the housing 11 and located within the power chamber 102. The housing 11 has a through hole 105. The drive rod 122 is disposed on the drive impeller 121 and passes through the through hole 105. After passing through the through hole 105, the drive rod 122 is connected to the transmission assembly 13. The housing 11 has a water inlet channel 106. The water inlet 101, the water inlet channel 106, and the power chamber 102 are sequentially connected.

[0084] Example 4
[0085] like Figure 17 As shown, this embodiment discloses a dishwasher, including: an inner tub assembly 100; a dish rack assembly 200 disposed on the inner tub assembly 100; and the aforementioned spray device 300 disposed on the inner tub assembly 100 and / or the dish rack assembly 200.
[0086] The second aspect of this application discloses a dishwasher that utilizes the reciprocating rotation of the spray assembly 2 of the spray device 300 to focus on rinsing specific areas within the dish rack assembly 200, such as areas with densely packed or heavily soiled dishes. This avoids the ineffective spraying of non-target areas, such as the walls of the inner drum assembly 100, by traditional spray structures, significantly improving cleaning efficiency and effectively reducing water waste. The separate arrangement of the power chamber 102 and the transmission chamber 104 further prevents food residue and other contaminants from entering the transmission chamber 104 and becoming difficult to clean, thus preventing the growth of viruses and bacteria.
