Description

Technical Field

[0001] The present invention relates to the field of dishwashers, and particularly to a spraying device and a dishwasher. Background Art

[0002] The power for the traditional dishwasher to drive the spraying device is mainly provided by a motor. When using a motor drive, it is necessary to ensure a very high protection level and insulation level for the motor, and there are strict requirements for the life and torque of the motor. To meet these requirements will surely make the product structure complex and the cost relatively high. Moreover, using a motor to drive the spraying device can only rotate 360 degrees, so that the spraying device will spray some parts in the dishwasher that do not need to be sprayed, resulting in unnecessary waste of washing water and low spraying efficiency. Summary of the Invention

[0003] Based on this, in view of the problem that the traditional dishwasher uses a drive to drive the spraying device, which causes the spraying device to spray some parts in the dishwasher that do not need to be sprayed, resulting in unnecessary waste of washing water and low spraying efficiency, it is necessary to provide a spraying device and a dishwasher.

[0004] A spraying device includes: a power source assembly, the power source assembly is provided with a water inlet and a water outlet, the power source assembly is provided with a power chamber, and the water inlet, the power chamber and the water outlet are sequentially communicated; a spraying assembly, the spraying assembly is arranged on the power source assembly, and the spraying assembly is communicated with the water outlet; a rotating member, the rotating member is arranged on the power source assembly, and when the power chamber inputs liquid, the power source assembly can drive the rotating member to rotate; a rocker, the rocker is arranged on the spraying assembly; a connecting member, the connecting member is respectively connected to the rotating member and the rocker; the rotating member can drive the spraying assembly to rotate relative to the power source assembly towards a first direction and a second direction, and the second direction is opposite to the first direction.

[0005] The first aspect of the present application discloses a spraying device. When washing water is introduced into the power chamber, the power source assembly can drive the rotating member, providing power for the rotation of the rotating member. This design replaces the traditional motor drive, eliminating the need to consider motor design factors and reducing production costs. Since the water outlet is connected to the power chamber and the spraying assembly is connected to the water outlet, the washing water used to provide kinetic energy can be transported to the spraying assembly through the water outlet for spraying, without causing waste of washing water. Through the sequential connection of the rotating member, the connecting member, and the rocker, which is similar to a crank-rocker mechanism, the spraying assembly can only reciprocate within a certain area, replacing the 360-degree rotation of the traditional spraying assembly. This prevents unnecessary waste of washing water by spraying areas in the dishwasher that do not require spraying. This design can effectively improve the spraying efficiency of the spraying device. For example, for some auxiliary spraying assemblies that only need to clean a part of the bowl basket or tray, this design enables them to focus on spraying specific areas without spraying the side walls and bottom walls of the inner cavity, resulting in high spraying efficiency and avoiding water resource waste.

[0006] In one embodiment, the movement trajectory of the rotating member is circular. Due to the circular movement trajectory of the rotating member, the rotating member can rotate unidirectionally and 360 degrees, enabling the connecting member to drive the spraying assembly to reciprocate under the drive of the rotating member, thereby improving the spraying efficiency.

[0007] In one embodiment, the cross-section of the connecting member is arc-shaped. With the arc-shaped cross-section of the connecting member, it better conforms to the relative movement trajectory between the rotating member and the rocker, can better adapt to the angular changes during the reciprocating swing of the spraying assembly, and improves the coordination of the overall mechanism. This design can ensure that the reciprocating rotation of the spraying assembly is smoother and more stable, with high spraying efficiency.

[0008] In one embodiment, one end of the connecting member is movably connected to the rotating member, and the other end of the connecting member is movably connected to the rocker. Through the sequential movable connection of the rotating member, the connecting member, and the rocker, it ensures that the continuous rotational movement of the rotating member is more smoothly converted into the reciprocating rotation of the spraying assembly. By connecting the rotating member and the rocker to the two ends of the connecting member respectively, the design is more reasonable, enabling more effective power transmission and effectively improving the spraying efficiency.

[0009] In one embodiment, one end of the rotating member is in transmission connection with the power source assembly, and the other end of the rotating member is movably connected to the connecting member. By connecting the two ends of the rotating member to the power source assembly and the connecting member respectively, the design is more reasonable and can effectively improve the power transmission efficiency, thereby improving the spraying efficiency.

[0010] In one embodiment, the spraying assembly includes an infusion channel and spraying holes. The number of the spraying holes is multiple, and the multiple spraying holes are sequentially arranged along the length direction of the spraying assembly. The water outlet, the infusion channel, and the multiple spraying holes are sequentially communicated. By arranging the multiple spraying holes sequentially along the length direction of the spraying assembly, for example, the multiple spraying holes are on the same straight line, replacing the dispersed and circumferential arrangement of the traditional spraying holes, which can avoid wasting washing water by outputting washing water in unnecessary directions. This design avoids dispersing unnecessary hydraulic pressure and can improve the spraying efficiency.

[0011] In one embodiment, the water outlet is located at the bottom of the power source assembly. By having the water outlet located at the bottom of the power source assembly, it is beneficial to prevent the residue of washing water.

[0012] In one embodiment, the rotating member is provided with a fitting hole, and the fitting hole can cooperate with the power source assembly.

[0013] In one embodiment, the rotating member includes a rotating portion and an assembling portion. The rotating portion is connected to the power source assembly, and the assembling portion is arranged on the rotating portion. The assembling portion is used to cooperate with the connecting member.

[0014] In one embodiment, the rotation angle of the spraying assembly is less than 180 degrees. When the rotation angle of the spraying assembly is less than 180 degrees, the rotation angle of the rocker is theoretically less than 180 degrees. This design enables the spraying assembly to only reciprocally rotate within a certain area, replacing the 360-degree rotation of the traditional spraying assembly, and preventing unnecessary waste of washing water by spraying on some parts in the dishwasher that do not require spraying.

[0015] In one embodiment, the connecting member is provided with multiple first adjustment holes, and all of the multiple first adjustment holes can cooperate with the rotating member. By enabling all of the multiple first adjustment holes to cooperate with the rotating member, the rotating member can be cooperated with a selected first adjustment hole according to requirements. This design enables the use of other first adjustment holes for cooperation even if one of the first adjustment holes is damaged, without the need to replace the connecting member, effectively improving the service life of the product.

[0016] In one embodiment, the multiple first adjustment holes are sequentially arranged along the extending direction of the connecting member. By arranging the multiple first adjustment holes sequentially along the extending direction of the connecting member, the angle range within which the spraying assembly can rotate when the rotating member is engaged with different first adjustment holes is different, and the spraying area of the spraying assembly can be correspondingly increased or decreased, suitable for more different tableware placement methods.

[0017] In one embodiment, when one of the multiple first adjustment holes cooperates with the rotating member, the maximum angle by which the spraying assembly can rotate is β1, and when another one of the multiple first adjustment holes cooperates with the rotating member, the maximum angle by which the spraying assembly can rotate is β2, and β2 is greater than β1. By having different angle ranges for the spraying assembly to rotate when the rotating member cooperates with different first adjustment holes, the spraying area of the spraying assembly can be increased or decreased accordingly, making it suitable for more different tableware placement methods, allowing for focused spraying on heavily soiled areas, and improving the tableware cleaning efficiency.

[0018] In one embodiment, one end of the rocker arm away from the spraying assembly is movably connected to the connecting member. By movably connecting one end of the rocker arm away from the spraying assembly to the connecting member, the design is more reasonable, the power transmission between the connecting member and the rocker arm is smoother, the reciprocating rotation efficiency of the spraying assembly is improved, and thus the spraying efficiency of the spraying assembly is enhanced.

[0019] In one embodiment, the rocker arm extends along the radial direction of the spraying assembly. By having the rocker arm extend along the radial direction of the spraying assembly, better power transmission can be achieved through the sequential connection of the rotating member, the connecting member, and the rocker arm to drive the spraying assembly to reciprocate and rotate, thereby enhancing the spraying efficiency.

[0020] In one embodiment, the connecting member is provided with multiple second adjustment holes, and the number of the second adjustment holes is multiple. The multiple second adjustment holes are arranged in sequence along the extending direction of the connecting member or the multiple second adjustment holes are arranged at intervals. All of the multiple second adjustment holes can cooperate with the rocker arm. When one of the multiple second adjustment holes cooperates with the rocker arm, the maximum angle by which the spraying assembly can rotate is β3, and when another one of the multiple second adjustment holes cooperates with the rocker arm, the maximum angle by which the spraying assembly can rotate is β4, and β4 is greater than β3. By having different angle ranges for the spraying assembly to rotate when the rocker arm cooperates with different second adjustment holes, the spraying area of the spraying assembly can be increased or decreased accordingly, making it suitable for more different tableware placement methods, allowing for focused spraying on heavily soiled areas, and improving the tableware cleaning efficiency.

[0021] In one embodiment, the power source assembly includes a housing, a driving assembly, and a transmission assembly. The housing is provided with the water inlet, the power chamber, and the water outlet. The housing is provided with a transmission chamber. The driving assembly is disposed on the housing and located within the power chamber. The transmission assembly is disposed on the housing and located within the transmission chamber. The transmission assembly is in transmission connection with the driving assembly, and the transmission assembly is in transmission connection with the rotating member. When liquid is input into the power chamber, the driving assembly can drive the transmission assembly, and finally drive the rotating member to rotate. It is possible to use the washing water that originally needs to be sprayed as power to provide kinetic energy for the driving assembly. This design replaces the traditional motor drive, does not need to consider the design factors of the motor, and the control method is simpler, more convenient, and more environmentally friendly. By having the driving assembly located within the power chamber and the transmission assembly located within the transmission chamber, and the power chamber and the transmission chamber are separately arranged, it is beneficial to prevent residues such as vegetable dregs from the cleaning from entering the transmission chamber and being difficult to clean, thereby generating viruses and bacteria.

[0022] In one embodiment, the housing includes a first housing member and a second housing member. The first housing member is provided with the water inlet, the power chamber, and the water outlet. The second housing member is disposed on the first housing member, and the second housing member and the first housing member enclose to form the transmission chamber. By having the first housing member provided with the power chamber and the second housing member and the first housing member enclosing to form the transmission chamber, the power chamber and the transmission chamber are separately arranged, which is beneficial to prevent residues such as vegetable dregs from the cleaning from entering the transmission chamber and being difficult to clean, thereby generating viruses and bacteria.

After passing through the perforation, the driving rod is connected to the transmission assembly. The housing is provided with a water inlet passage.

The extending direction of the water inlet passage is tangent to the outer circle of the driving impeller. The housing is provided with a water outlet passage. The power chamber, the water outlet passage, and the water outlet are sequentially communicated. The extending direction of the water outlet passage is tangent to the outer circle of the driving impeller. By having the extending directions of the water inlet passage and the water outlet passage tangent to the outer circle of the driving impeller, the liquid enters from the tangential direction of the driving impeller, which can more effectively drive the driving impeller. By connecting the transmission assembly to the driving rod, the driving impeller can drive the transmission assembly to rotate after rotation. This design replaces the traditional motor drive method, and the control method is simpler, more convenient, and has a lower cost.

[0024] In one embodiment, the transmission assembly includes an input gear, a first support shaft, a second support shaft, and a transmission gear.

By using the input gear, the transmission gear, and one of the first support shaft or the second support shaft as an output shaft to be in transmission connection with the rotating member, effective transmission of power can be achieved, enabling the rotating member to rotate reliably and stably under the drive of the transmission assembly.

[0025] In one embodiment, the transmission gear includes a first gear. The first gear is disposed 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.

[0056] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0057] Embodiment 1

[0058] As Figure 1 and Figures 3 - 5 shown, this embodiment discloses a spraying device, including: a power source assembly 1, the power source assembly 1 is provided with a water inlet 101 and a water outlet 103, the power source assembly 1 is provided with a power cavity 102, and the water inlet 101, the power cavity 102 and the water outlet 103 are communicated in sequence; a spraying assembly 2, the spraying assembly 2 is arranged on the power source assembly 1, and the spraying assembly 2 is communicated with the water outlet 103; a rotating member 3, the rotating member 3 is arranged on the power source assembly 1, and when the power cavity 102 inputs liquid, the power source assembly 1 can drive the rotating member 3 to rotate; a rocker 4, the rocker 4 is arranged on the spraying assembly 2; a connecting member 5, the connecting member 5 is respectively connected with the rotating member 3 and the rocker 4; the rotating member 3 can drive the spraying assembly 2 to rotate relative to the power source assembly 1 towards a first direction and a second direction, and the second direction is opposite to the first direction.

[0059] The first aspect of the present application discloses a spraying device. When washing water is introduced into the power chamber 102, the power source assembly 1 can drive the rotating member 3, providing power for the rotation of the rotating member 3. This design replaces the traditional motor drive, eliminating the need to consider motor design factors and reducing production costs. Since the water outlet 103 is in communication with the power chamber 102 and the spraying assembly 2 is in communication with 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, without causing waste of washing water. Due to the sequential connection of the rotating member 3, the connecting member 5, and the rocker 4, which is similar to a crank-rocker mechanism, the spraying assembly 2 can only reciprocally rotate within a certain area, replacing the 360-degree rotation of the traditional spraying assembly 2. This prevents unnecessary waste of washing water by spraying on parts of the dishwasher that do not require spraying. This design can effectively improve the spraying efficiency of the spraying device. For example, for some auxiliary spraying assemblies 2 that only need to clean a part of the bowl basket or tray, this design enables them to focus on spraying specific areas without spraying on the side walls and bottom walls of the inner liner, etc., resulting in high spraying efficiency and avoiding waste of water resources.

[0060] In addition to the features of the above embodiment, the present embodiment further defines that: the movement trajectory of the rotating member 3 is circular. Due to the circular movement trajectory of the rotating member 3, the rotating member 3 can rotate unidirectionally and can rotate 360 degrees, enabling the connecting member 5 to drive the spraying assembly 2 to reciprocally rotate under the drive of the rotating member 3, thereby improving the spraying efficiency.

[0061] As Figure 7 shown, in addition to the features of the above embodiment, the present embodiment further defines that: the cross-section of the connecting member 5 is arc-shaped. Due to the arc-shaped cross-section of the connecting member 5, it better conforms to the relative movement trajectory between the rotating member 3 and the rocker 4, can better adapt to the angular changes during the reciprocating swing of the spraying assembly 2, and improves the coordination of the overall mechanism. This design can ensure that the reciprocating rotation of the spraying assembly 2 is smoother and more stable, with high spraying efficiency.

[0062] As Figure 1 and Figure 3 shown, in addition to the features of the above embodiment, the present embodiment further defines 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 4. Through the sequential movable connection of the rotating member 3, the connecting member 5, and the rocker 4, it ensures that the continuous rotational movement of the rotating member 3 is more smoothly converted into the reciprocating rotation of the spraying assembly 2. By connecting the rotating member 3 and the rocker 4 to the two ends of the connecting member 5 respectively, the design is more reasonable, enabling more effective power transmission and effectively improving the spraying efficiency.

[0063] As Figure 1 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further defines that one end of the rotating member 3 is in transmission connection with the power source assembly 1, and the other end of the rotating member 3 is movably connected to the connecting member 5. By connecting the two 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] As Figure 8 shown, in addition to the features of the above embodiments, this embodiment further defines that the spraying assembly 2 includes an infusion channel 201 and spraying holes 202. The number of the spraying holes 202 is multiple, and the multiple spraying holes 202 are arranged in sequence along the length direction of the spraying assembly 2. The water outlet 103, the infusion channel 201 and the multiple spraying holes 202 are communicated in sequence. By arranging the multiple spraying holes 202 in sequence along the length direction of the spraying assembly 2, for example, the multiple spraying holes 202 are on the same straight line, replacing the dispersed and circumferential arrangement of the traditional spraying holes 202, which can avoid wasting the washing water by outputting the washing water in unnecessary directions. This design avoids dispersing unnecessary hydraulic pressure and can improve the spraying efficiency.

[0065] As Figure 9 shown, in addition to the features of the above embodiments, this embodiment further defines that the water outlet 103 is located at the bottom of the power source assembly 1. By having the water outlet 103 located at the bottom of the power source assembly 1, it is beneficial to prevent the residue of the washing water.

[0066] As Figure 2 and Figure 6 shown, in addition to the features of the above embodiments, this embodiment further defines that the rotating member 3 is provided with an adaptation hole 301, and the adaptation hole 301 can cooperate with the power source assembly 1.

[0067] As Figure 2 and Figure 6 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 assembling part 32. The rotating part 31 is connected to the power source assembly 1, and the assembling part 32 is arranged on the rotating part 31. The assembling part 32 is used to cooperate with the connecting member 5.

[0068] In addition to the features of the above embodiments, this embodiment further defines that the rotation angle of the spraying assembly 2 is less than 180 degrees. The rotation angle of the spraying assembly 2 is less than 180 degrees, and the rotation angle of the rocker 4 is theoretically less than 180 degrees. This design enables the spraying assembly 2 to only rotate reciprocally within a certain area, replacing the 360-degree rotation of the traditional spraying assembly 2, and will not spray some parts in the dishwasher that do not need to be sprayed, resulting in unnecessary waste of washing water.

[0069] As Figure 2 and Figure 7 shown, in addition to the features of the above embodiments, this embodiment further defines that: the connecting member 5 is provided with a first adjustment hole 501, and the number of the first adjustment holes 501 is multiple, and all of the multiple first adjustment holes 501 can cooperate with the rotating member 3. By enabling all of the multiple first adjustment holes 501 to cooperate with the rotating member 3, the rotating member 3 can be matched with the selected first adjustment hole 501 according to requirements. This design enables the use of other first adjustment holes 501 for cooperation even if one of the first adjustment holes 501 is damaged, without the need to replace the connecting member 5, effectively improving the service life of the product.

[0070] As Figure 2 and Figure 7 shown, in addition to the features of the above embodiments, this embodiment further defines that: the multiple first adjustment holes 501 are sequentially arranged along the extending direction of the connecting member 5. By arranging the multiple first adjustment holes 501 sequentially along the extending direction of the connecting member 5, the angle range that the spraying assembly 2 can rotate when the rotating member 3 is engaged with different first adjustment holes 501 is different, and the spraying area of the spraying assembly 2 can be increased or decreased accordingly, suitable for more different tableware placement methods.

[0071] In addition to the features of the above embodiments, this embodiment further defines that: when one of the multiple first adjustment holes 501 cooperates with the rotating member 3, the maximum angle that the spraying assembly 2 can rotate is β1, and when another one of the multiple first adjustment holes 501 cooperates with the rotating member 3, the maximum angle that the spraying assembly 2 can rotate is β2, and β2 is greater than β1. By enabling the angle range that the spraying assembly 2 can rotate to be different when the rotating member 3 cooperates with different first adjustment holes 501, the spraying area of the spraying assembly 2 can be increased or decreased accordingly, suitable for more different tableware placement methods, and the heavily polluted area can be focused on spraying, improving the tableware cleaning efficiency.

[0072] As Figure 1 and Figure 3 shown, in addition to the features of the above embodiments, this embodiment further defines that: one end of the rocker 4 away from the spraying assembly 2 is movably connected to the connecting member 5. By movably connecting one end of the rocker 4 away from the spraying assembly 2 to the connecting member 5, the design is more reasonable, the power transmission between the connecting member 5 and the rocker 4 is smoother, the reciprocating rotation efficiency of the spraying assembly 2 is improved, and thus the spraying efficiency of the spraying assembly 2 is improved.

[0073] As Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines that: the rocker 4 extends along the radial direction of the spray assembly 2. By extending the rocker 4 along the radial direction of the spray assembly 2, the sequential connection of the rotating member 3, the connecting member 5 and the rocker 4 can achieve better power transmission to drive the spray assembly 2 to rotate reciprocally, improving the spraying efficiency.

[0074] In addition to the features of the above embodiments, this embodiment further defines that: the connecting member 5 is provided with second adjustment holes, the number of the second adjustment holes is multiple, the multiple second adjustment holes are sequentially arranged along the extending direction of the connecting member 5 or the multiple second adjustment holes are arranged at intervals, the multiple second adjustment holes can all cooperate with the rocker 4, when one of the multiple second adjustment holes cooperates with the rocker 4, the maximum angle that the spray assembly 2 can rotate is β3, when another one of the multiple second adjustment holes cooperates with the rocker 4, the maximum angle that the spray assembly 2 can rotate is β4, and β4 is greater than β3. By different angles that the spray assembly 2 can rotate when the rocker 4 cooperates with different second adjustment holes, the spraying area of the spray assembly 2 can be increased or decreased accordingly, which is applicable to more different tableware placement methods, can focus on spraying the heavily polluted areas, and improves the tableware cleaning efficiency.

[0075] As Figures 11 - 13 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the power source assembly 1 includes a housing 11, a driving 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 provided with a transmission chamber 104, the driving assembly 12 is arranged on the housing 11 and is located in the power chamber 102, the transmission assembly 13 is arranged on the housing 11 and is located in the transmission chamber 104, the transmission assembly 13 is in transmission connection with the driving assembly 12, and the transmission assembly 13 is in transmission connection with the rotating member 3. When liquid is input into the power chamber 102, the driving assembly 12 can drive the transmission assembly 13, and finally drive the rotating member 3 to rotate. The washing water that originally needs to be sprayed can be used as power to provide kinetic energy for the driving assembly 12. This design replaces the traditional motor drive, does not need to consider the design factors of the motor, and the control method is simpler and more convenient and more environmentally friendly.
