[0085] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0086] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0087] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0088] This disclosure provides a dishwasher that can be used in home kitchens or restaurants to automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks.

[0089] like Figures 1 to 3 As shown, the dishwasher 10 includes a cleaning module 100, a dish rack 200, an inner liner 300, and a housing 400. The housing 400 has multiple receiving portions in the height direction, and each receiving portion has an inner liner 300. Multiple dish racks 200 are correspondingly arranged inside the multiple inner liners 300 for holding bowls, chopsticks, plates, dishes, knives, forks, and other tableware waiting to be cleaned. Multiple cleaning modules 100 are fixed inside the inner liners 300, below the dish racks 200, i.e., below the tableware to be cleaned, to spray cleaning liquid onto the tableware to be cleaned, thereby making it easier to clean the tableware.

[0090] like Figure 3 As shown, the dishwasher 10 may include, Figure 3The two cleaning spaces shown, namely the dishwasher 10, can be equipped with a double-layer cleaning module 100, and the housing 400 has two inner tubs 300, so that different types of tableware can be placed on different dish racks 200 by opening different drawers, thereby classifying and cleaning different types of tableware and improving cleaning efficiency. Of course, three, four or more inner tubs 300 can also be set, with one cleaning module 100 in each inner tub 300, and this disclosure does not limit this.

[0091] Specifically, the dishwasher 10 also includes: a water circuit module, which includes a water supply component and a water return component. The water supply component includes a water supply pipe connected to multiple cleaning modules. The water supply component is configured to provide cleaning fluid to any one or any multiple cleaning modules. The water return component includes a water return pipe 510 through which multiple inner tanks drain water.

[0092] The dishwasher disclosed herein can supply liquid to any one or more cleaning modules 100 in each inner tank 300 through the water supply component in the water circuit module, so that each cleaning module 100 can perform cleaning operations individually or simultaneously; through the return water pipe 510, the wastewater in each inner tank 300 after cleaning the dishes can be discharged. Therefore, by setting multiple inner tanks 300, and by opening different drawers to place dishes to be washed on different dish racks 200, different types of dishes can be sorted and cleaned, thereby improving the cleaning efficiency of the dishwasher.

[0093] Specifically, such as Figures 3-6 As shown, the water supply pipe and the return water pipe 510 are formed on the same guide member 700. A back plate is provided between the two cleaning modules. The back plate, which serves as the guide member 700, contains water channels. The water supply pipe and the return water pipe 510 are formed on the back plate, which improves the structural compactness and avoids the water supply pipe and the return water pipe 510 occupying extra space. This allows the dishwasher to be relatively small in size, making it easier for users to install and use.

[0094] Specifically, such as Figures 4-6 As shown, the water return assembly also includes a filter assembly 520. Wastewater in the inner tank 300 enters the return water pipe 510 through the inlet 511, and the filter assembly 520 filters the wastewater discharged through the drain outlet 5120 of the return water pipe 510. By installing the filter assembly 520, wastewater from washing dishes can be filtered, thus removing food scraps and other larger solids, preventing blockage of the drain pipe.

[0095] Specifically, the dishwasher's water supply system may include a clean water path and a circulating water path. The clean water path provides unused cleaning solution, while the circulating water path allows for reuse of the cleaning solution, reducing the amount of cleaning solution needed. The cleaning solution may be clean water or detergent.

[0096] Specifically, such as Figures 4-6 As shown, the water supply assembly includes a circulation pump 610, and the water supply pipeline includes multiple first water channels 631. The outlets of the multiple first water channels 631 are respectively connected to multiple cleaning modules to provide cleaning fluid to the multiple cleaning modules. The inlets of the multiple first water channels 631 are connected to the outlet of the circulation pump 610, and the inlet of the circulation pump 610 is connected to the outlet of the filter assembly 520. By setting the circulation pump 610 and the multiple first water channels 631 to form a circulating water channel, the cleaning fluid filtered by the filter assembly 520 can be sprayed out again through the cleaning modules to achieve multiple cleaning of tableware. The setting of the filter assembly 520 can also prevent the cleaning modules from being blocked by the cleaning fluid during multiple recycling processes.

[0097] Among them, such as Figure 4 and Figure 5 As shown, the water supply assembly also includes a first water distribution valve 641. The inlet of the first water distribution valve 641 is connected to the outlet of the circulating pump 610, and multiple outlets of the first water distribution valve 641 are connected one-to-one with the inlets of multiple first water passages 631. The first water distribution valve 641 is configured to control any one outlet to be in a closed or open state. Through the setting of the first water distribution valve 641, any one or more of the multiple cleaning modules can perform spraying operations. The first water distribution valve 641 can be an electrically controlled valve, connected to the controller of the dishwasher 10, allowing the user to operate and control it via the control panel.

[0098] Specifically, such as Figures 4-6 As shown, the water supply assembly also includes a water inlet 620, and the water supply pipeline includes multiple second water channels 632. The outlets of the multiple second water channels 632 are connected to multiple cleaning modules one by one, and the inlets of the multiple second water channels 632 are connected to the liquid outlet of the water inlet 620. The liquid inlet of the water inlet 620 is used to connect to external cleaning liquid. By setting up the water inlet 620 and the multiple second water channels 632, a clean water channel is formed, which can spray clean water or cleaning agent onto the tableware to be cleaned.

[0099] The water inlet 620 includes a clean water inlet, a detergent inlet, and a liquid outlet. The water inlet 620 is configured to control the connection between the clean water inlet and the liquid outlet, or between the detergent inlet and the liquid outlet, or to disconnect the liquid outlet from both the clean water inlet and the detergent inlet. For example, detergent can be supplied through the water inlet 620 to clean the tableware first. Then, the detergent can be circulated through a water circulation system to clean the tableware multiple times. Finally, clean water supplied by the water inlet 620 can be used to rinse away any remaining detergent.

[0100] Among them, such as Figure 4 As shown, the water supply assembly also includes a liquid storage tank 660, which includes at least a detergent container, and the detergent inlet of the water inlet 620 is connected to the detergent container.

[0101] like Figure 4 and Figure 5 As shown, the water supply assembly also includes a second water distribution valve 642. The inlet of the second water distribution valve 642 is connected to the outlet of the water inlet 620, and multiple outlets of the second water distribution valve 642 are connected one-to-one with the inlets of multiple second water passages 632. The second water distribution valve 642 is configured to control any one outlet to be in a closed or open state. Through the setting of the second water distribution valve 642, any one or more of the multiple cleaning modules can perform spraying operations. The second water distribution valve 642 can be an electrically controlled valve, which, by connecting to the dishwasher's controller, allows the user to operate and control it via the control panel.

[0102] like Figure 4 and Figure 5 As shown, the water supply assembly also includes a booster 650, which is connected between the inlet 620 and the second water distribution valve 642. The booster 650 is configured to increase the water pressure of the cleaning fluid passing between the inlet 620 and the second water distribution valve 642, so that the cleaning fluid sprayed through the cleaning module has a higher jet velocity, thereby improving the cleaning effect on the tableware. The booster 650 can be a booster pump, which has high reliability, good pressurization effect, and is easy to control the pressure.

[0103] Specifically, such as Figure 4 and Figure 5 As shown, the water return assembly also includes a drain pump 530, the inlet of which is connected to the drain outlet of the filter assembly 520. After the dishes are washed, the wastewater is filtered by the filter assembly 520 and then discharged through the drain pump 530.

[0104] Among them, such as Figure 7 and Figure 8 As shown, the filter assembly 520 includes a filter box 521 and a filter screen 522. The filter box 521 is detachably connected to the housing 400. The opening of the filter box 521 communicates with the drain outlet 512. The filter screen 522 is disposed in the filter box 521. Wastewater flowing in through the drain outlet 512 passes through the filter screen 522 and is discharged from the filter assembly 520. By providing a filter box 521 that is detachably connected to the housing 400, it is convenient to clean the filtered debris.

[0105] The filter screen 522 is detachably housed within the filter box 521. This detachable connection facilitates cleaning of debris from the filter screen 522 and also makes replacement of the damaged filter screen 522 easier, thus improving maintenance efficiency. Of course, the filter screen 522 and the filter box 521 can also be a single, integrated structure; this disclosure does not impose any limitations on this.

[0106] Specifically, the water return assembly also includes a slag remover 540, such as Figure 7and Figure 8 As shown, the food scraper 540 is connected to the filter screen 522, for example, at the bottom of the filter screen 522. Wastewater from washing dishes usually contains solid food scraps, which the filter screen 522 can filter out. The food scraper 540 connected to the filter screen 522 can then pulverize the filtered solid food scraps, breaking them down into smaller pieces, which are then discharged by the drain pump. This avoids the need for the user to manually clean the food scraps filtered from the filter screen 522, increasing the automation of the dishwasher and improving the user experience. It is understandable that the food scraper 540 can also be located at the top of the filter screen 522, first pulverizing the food scraps into finer pieces that can pass through the filter screen 522, and then discharging them by the drain pump, preventing the drain pump from becoming clogged due to incomplete pulverization by the food scraper 540. Furthermore, the user can remove at least one of the food scraper 540 and the filter screen 522 from the return water assembly for cleaning.

[0107] Generally, to improve kitchen space utilization and reduce the footprint of the dishwasher 10, it can be integrated into or installed in a kitchen cabinet or sink (also known as a dishwashing basin or sink). The overall outline of the dishwasher 10 needs to match the cabinet or sink, hence its square shape. The inner drum 300 of the dishwasher 10 typically opens by pulling out or flipping, allowing users to place dishes to be washed on the dish rack 200. Simultaneously, to ensure the dish rack 200 has a sufficiently large capacity and improves washing efficiency, the horizontal cross-section of the inner drum 300 is also square or rectangular, maximizing its size and cleaning efficiency.

[0108] like Figure 9 As shown, in related technologies, the spray section is centered on the center of the first spray area S1, with the arm length of the spray arm as the radius, rotating to form a circular first spray area S1. The first spray area S1 cannot cover the four corners of the rectangular inner tank 300, thus creating blind spots for hygiene. If the length of the cleaning arm is directly extended, for example, extending the first spray area S1 to the second spray area S2, the cleaning arm will inevitably interfere with the movement of the inner tank wall 310 of the dishwasher 10, causing the dishwasher 10 to malfunction. Regarding... Figure 9 As shown, embodiments of this disclosure provide a cleaning module.

[0109] like Figure 10 and Figure 11 As shown, the cleaning module 100 includes a support part 110, a transmission part 120, and a spraying part 130. The transmission part is rotatably mounted on the support part 110, and the spraying part 130 is rotatably mounted on the transmission part 120. The rotating shaft of the spraying part 130 is spaced apart from and parallel to the rotating shaft of the transmission part 120.

[0110] like Figure 10 As shown, in one embodiment, the spray unit 130 includes a rotating shaft 132 and at least one first spray arm 131. The first spray arm 131 can rotate around the rotating shaft 132 with the rotating shaft 132 as the center and the arm length of the first spray arm 131 as the radius, driven by the transmission unit 120, to cover... Figure 4 The first spray zone S1 is shown. The transmission unit 120 can be an eccentric arm.

[0111] like Figure 10 As shown, in one embodiment, the first spray arm 131 rotates around the rotating shaft 132 with the arm length of the first spray arm 131 as the radius, driven by the transmission unit 120. Simultaneously, the rotating shaft 132 also rotates around the axis of the transmission unit 120, further driving the first spray area S1 formed by the first spray arm 131 to rotate under the drive of the transmission unit 120, thereby forming an area larger than... Figure 4 The spray area of ​​the first spray area S1 shown can, for example, basically cover the entire interior of the bladder wall 310, improving the cleaning effect and reducing dead corners.

[0112] To facilitate reader comprehension, the following is explained using... Figure 10 Taking the first spray arm 131 as an example, the working principle of the spray arm will be explained. Figure 10 As shown, the first spray arm 131 is equipped with spray nozzles. By providing spray nozzles on the first spray arm 131, spraying operations can be performed on various positions within its coverage area during the rotation of the first spray arm 131, thereby spraying cleaning fluid onto the tableware to be cleaned on the dish rack 200 for cleaning. The cleaning fluid can be water or a cleaning solution, and different spray nozzles can spray different cleaning fluids; this disclosure does not impose any limitations on this.

[0113] The first spray arm 131 may have multiple spray nozzles, which can be arranged in rows or columns along the extension direction of the first spray arm 131. Through these spray nozzles, the first spray arm 131 can spray liquid onto the spray area it rotates to cover, thereby improving the cleaning effect.

[0114] The sizes of the multiple spray nozzles can be the same or different. For example, in the extension direction of the first spray arm 131, the diameter of the spray nozzle closer to the rotating shaft 132 can be larger than the diameter of the spray nozzle farther from the rotating shaft 132. Since the first spray arm 131 is usually supplied with liquid through the side closer to the rotating shaft 132, the liquid supply pressure on the side closer to the rotating shaft 132 is relatively high. By setting spray nozzles of different sizes, the amount of liquid sprayed from each spray nozzle can be the same or basically the same, thereby improving the cleaning effect.

[0115] In addition, such as Figure 11As shown, the cleaning module 100 also includes a first drive assembly 140 and a second drive assembly 150. The first spray arm 131 rotates about the pivot 132 under the drive of the first drive assembly 140. The transmission part 120 rotates relative to the support part 110 under the drive of the second drive assembly 150. Hereinafter, it will be explained by... Figures 12 to 19 The possible configuration of the first drive component 140 is described in detail.

[0116] In one embodiment, such as Figure 12 As shown, the first drive assembly 140 includes a first gear 141, a second gear 142, and at least one first connecting gear 143. The first gear 141 is fixed on the support 110 and coaxial with the shaft of the transmission 120. The second gear 142 and at least one first connecting gear 143 are rotatably mounted on the transmission 120, and the second gear 142 is coaxial with and fixedly connected to the shaft of the spray 130. The first gear 141, the second gear 142, and at least one first connecting gear 143 are all external gears. The first gear 141 and the second gear 142 mesh through an odd number of first connecting gears 143, that is, the first gear 141 and the second gear 142 rotate in the same direction, thereby causing the second gear 142 to rotate in the opposite direction to the transmission 120. Since the second gear 142 rotates synchronously with the spray 130, the spray 130 rotates in the opposite direction to the transmission 120.

[0117] The gear ratio between the first gear 141 and the second gear 142 is 4:3. Since the first gear 141 is fixed to the support portion 110, the transmission portion 120, which serves as the housing, can rotate around its own axis. This allows the free end of the transmission portion 120, connected to the rotating shaft 132 of the spray portion 130, to rotate 90° clockwise, while the first spray arm 131 of the spray portion 130 rotates 30° counterclockwise. Thus, when the first spray arm 131 rotates one revolution within a square with side length R, the transmission portion 120 can rotate three revolutions in the opposite direction.

[0118] In one embodiment, such as Figure 11 As shown, the transmission unit 120 includes an upper housing 121, a lower housing 122 and an intermediate housing 123. The first gear 141, the second gear 142 and the first connecting gear 143 are disposed in the receiving portion formed by the intermediate housing 123 and the lower housing 122, forming a sealed installation of the first drive assembly 140, thereby improving the reliability and service life of the first drive assembly 140 and reducing maintenance costs.

[0119] The lower housing 122 has a pivot hole 125. The first gear 141 is engaged with the mounting shaft 111 of the support 110, allowing it to rotate coaxially with the transmission 120. During the rotation of the transmission 120, the first connecting gear 143 is driven to rotate, which in turn drives the second gear 142 to rotate, ultimately driving the rotation of the spray section 130. Therefore, the rotation of the spray section 130 is actively controlled, allowing for adjustment of the rinsing time for the corner areas of the inner tank 300 or selection of rinsing areas, thus improving the overall cleaning performance of the dishwasher 10. The first gear 141 can be glued, welded, or engaged with the mounting shaft 111, or it can be integrally formed with the mounting shaft 111.

[0120] In another embodiment, such as Figure 13 As shown, the first drive assembly 140 may include a first synchronous pulley 144, a second synchronous pulley 145, and a first synchronous toothed belt 146. The first synchronous pulley 144 is fixed on the support 110 and coaxial with the shaft of the transmission 120. The second synchronous pulley 145 is rotatably mounted on the transmission 120 and coaxial with and fixedly connected to the shaft of the spray 130. The first synchronous pulley 144 and the second synchronous pulley 145 are synchronously driven through the first synchronous toothed belt 146. By making the first synchronous pulley 144 and the second synchronous pulley 145 synchronously driven through the first synchronous toothed belt 146, the first synchronous pulley 144 and the second synchronous pulley 145 rotate in the same direction, the second synchronous pulley 145 rotates in the opposite direction to the transmission 120, and the second synchronous pulley 145 rotates synchronously with the spray 130, that is, the spray 130 rotates in the opposite direction to the transmission 120.

[0121] The gear ratio between the first synchronous pulley 144 and the second gear 142 is 4:3, which allows the first spray arm 131 of the spray unit 130 to rotate 30° counterclockwise when the free end of the transmission part 120 connected to the rotating shaft 132 of the spray unit 130 rotates 90° clockwise. This means that when the first spray arm 131 rotates one revolution within a square with side length R, the transmission part 120 can rotate three revolutions in the opposite direction.

[0122] In another embodiment, the first drive assembly 140 may include a first drive motor, and the second drive assembly includes a second drive motor. The first drive motor drives the spray section 130 to rotate, and the second drive motor drives the transmission section 120 to rotate. The first drive motor is fixedly mounted on the transmission section 120 and rotates with the transmission section 120. Through the cooperation of the first drive motor and the second drive motor, the second drive motor only drives the transmission section to rotate, which can realize direct driving and control of the rotation of the spray section 130. That is, the spray section 130 can be actively controlled in an electronically controlled manner as the transmission section 120 rotates. Therefore, the rinsing time of the corner areas of the inner tank 300 or the rinsing area can be adjusted or the rinsing area can be selected, thereby improving the cleaning performance of the dishwasher 10.

[0123] Furthermore, in one embodiment, such as Figures 14 to 16 As shown, the first drive assembly 140 includes a first gear 141 and a second gear 142. The first gear 141 is fixed to the support portion 110 and coaxial with the shaft of the transmission portion 120, while the second gear 142 is fixed to the spray portion 130 and coaxial with the shaft 132 of the spray portion 130. The first gear 141 is an internal gear, and the second gear 142 is an external gear; some of the external teeth of the first gear 141 mesh with some of the internal teeth of the second gear 142. Therefore, when the transmission portion 120 rotates relative to the support portion 110, the second gear 142 rotates relative to the first gear 141, thereby driving the spray portion 130 to rotate relative to the transmission portion 120, enabling the spray portion 130 to rotate and form a cleaning area covering a certain radius. Furthermore, driven by the transmission portion 120, the spray portion 130 can rotate around the center point of the transmission portion 120, thereby increasing the area of ​​the cleaning area covered by the spray portion 130 and improving the cleaning effect. The following will explain... Figures 12 to 14 Further explanation of the cleaning module 100.

[0124] Figure 15 This is a schematic diagram showing the connection between the second gear 142 and the spray unit 130 according to one embodiment of this disclosure. Figure 15 As shown, the spray unit 130 includes a rotating shaft 132 and a first spray arm 131. The spray unit 130 is rotatably mounted to the transmission unit 120 via the rotating shaft 132, and the first spray arm 131 extends radially along the rotating shaft 132. A second gear 142 is fixed to the spray unit 130 and coaxial with the rotating shaft 132 of the support unit 110. The second gear 142 and the spray unit 130 can be integrally formed to avoid reducing the coaxiality between them due to long-term use. Of course, it is understood that the second gear 142 and the spray unit 130 can also be fixedly connected by means of bonding, welding, snap-fitting, threaded connection, etc.

[0125] Figure 16This is a schematic diagram showing the connection between the first gear 141 and the support portion 110 according to an embodiment of this disclosure. Figure 16 As shown, the first gear 141 is fixedly connected to the support portion 110. The first gear 141 and the support portion 110 can be integrally formed to avoid reducing the coaxiality between the shaft of the transmission portion 120 on the first gear 141 and the support portion 110 due to long-term use. Of course, it is understood that the first gear 141 and the support portion 110 can also be fixedly connected by means of bonding, welding, snap-fitting, threaded connection, etc.

[0126] Figure 17 and Figure 18 This is a schematic diagram of a transmission unit 120 and a spray unit 130 provided in one embodiment of the present disclosure. Figure 19 This is a schematic diagram of a support portion 110 provided according to an embodiment of the present disclosure. Figures 17 to 19 As shown, the support part 110 is provided with a mounting shaft 111, and the transmission part 120 is provided with a rotating shaft hole 125. The transmission part 120 is rotatably connected to the mounting shaft 111 through the rotating shaft hole 125. Hereinafter, it will be explained by... Figures 20 to 30 The possible configuration of the flow channels in the cleaning module 100 is described in detail.

[0127] In one embodiment, such as Figure 20 As shown, the first spray arm 131 is provided with a first spray nozzle 1311 and a second spray nozzle 1312. By providing the first spray nozzle 1311 and the second spray nozzle 1312 on the first spray arm 131, spraying operations can be carried out at various positions in its coverage area during the rotation of the first spray arm 131, thereby spraying cleaning liquid onto the tableware to be cleaned on the dish rack 200 to clean the tableware.

[0128] Specifically, such as Figure 20 As shown, the first spray nozzles 1311 can be arranged along the extension direction of the first spray arm 131, so that multiple first spray nozzles 1311 are distributed in a row. This allows the multiple first spray nozzles 1311 to spray liquid at various positions within the first spray area S1 covered by the rotating first spray arm 131, thus improving the cleaning effect. The multiple first spray nozzles 1311 can be the same or different in size. For example, in the extension direction of the first spray arm 131, the diameter of the first spray nozzle 1311 closer to the rotating shaft 132 among two adjacent first spray nozzles 1311 may differ. Since the first spray arm 131 is usually supplied with liquid from the side closest to the rotating shaft 132, the liquid supply pressure on the side closest to the rotating shaft 132 is relatively high. By setting multiple first spray nozzles 1311 of different sizes, the spray volume of each multiple first spray nozzle 1311 can be the same or substantially the same, thereby improving the cleaning effect.

[0129] Specifically, the second spray nozzles 1312 can be arranged along the extension direction of the first spray arm 131, so that multiple second spray nozzles 1312 are distributed in a row. This allows the multiple second spray nozzles 1312 to spray liquid at various positions within the first spray area S1 covered by the rotation of the first spray arm 131, thereby improving the cleaning effect. The multiple second spray nozzles 1312 can be the same or different in size. For example, in the extension direction of the first spray arm 131, among two adjacent multiple second spray nozzles 1312, the diameter of the multiple second spray nozzles 1312 closer to the rotating shaft 132 can be larger than the diameter of the multiple second spray nozzles 1312 farther from the rotating shaft 132. Since the first spray arm 131 is usually supplied with liquid from the side closer to the rotating shaft 132, the liquid supply pressure on the side closer to the rotating shaft 132 is relatively high. By setting multiple second spray nozzles 1312 of different sizes, the spray volume of each multiple second spray nozzle 1312 can be the same or substantially the same, thereby improving the cleaning effect.

[0130] For example Figures 21 to 23 As shown, the rotating shaft 132 of the spray section 130 can be hollow to connect to the second flow channel within the transmission section 120. The spray section 130 may include a snap-fit ​​upper spray section shell 133 and a snap-fit ​​spray section lower spray section shell 134. An independent first flow channel 135 and a second flow channel 136 are formed between the snap-fit ​​upper spray section shell 133 and the lower spray section shell 134. A first spray nozzle 1311 and a second spray nozzle 1312 are provided on the upper spray section shell 133; as shown... Figure 23 and Figure 24 As shown, the hollow rotating shaft 132 has a first liquid inlet channel 1321 and a second liquid inlet channel 1322. The first liquid inlet channel 1321 is connected to the first flow channel 135, and the second liquid inlet channel 1322 is connected to the second flow channel 136, thereby supplying liquid to the first spray arm 131 through the first liquid inlet channel 1321 and the second liquid inlet channel 1322.

[0131] The inlets of the first liquid inlet channel 1321 and the second liquid inlet channel 1322 corresponding to the first flow channel 135 and the second flow channel 136 on each first spray arm 131 are distributed along the axial direction of the rotating shaft 132, that is, the inlets of the first flow channel 135 and the second flow channel 136 are distributed along the axial direction of the rotating shaft 132.

[0132] For example Figures 24 to 26As shown, the support part 110 is provided with a mounting shaft 111, and the transmission part 120 is provided with a rotating shaft hole 125. The transmission part 120 is mounted on the mounting shaft 111 through the rotating shaft hole 125 and is rotatably connected to the support part 110. The support part 110 is provided with independent third flow channel 115 and fourth flow channel 116. The mounting shaft 111 is provided with a third liquid inlet channel 113 and a fourth liquid inlet channel 114. The third flow channel 115 is connected to the third liquid inlet channel 113, and the fourth flow channel 116 is connected to the fourth liquid inlet channel 114. That is, the outlets of the third flow channel 115 and the fourth flow channel 116 are located on the mounting shaft 111.

[0133] Among them, the outlets of the third liquid inlet channel 113 and the fourth liquid inlet channel 114 corresponding to the third flow channel 115 and the fourth flow channel 116 on the support part 110 are distributed along the axial direction of the mounting shaft 111, that is, the inlets of the third flow channel 115 and the fourth flow channel 116 are distributed along the axial direction of the mounting shaft 111 on the mounting shaft 111.

[0134] In one embodiment, the cleaning module 100 further includes a flow guide, through which independent fifth and sixth flow channels are formed. The flow guide is sleeved on the mounting shaft 111 of the support portion 110 and the rotating shaft 132 of the spray portion 130. The fifth flow channel connects the first flow channel 135 and the third flow channel, and the sixth flow channel connects the second flow channel 136 and the fourth flow channel 116. Wherein, as... Figure 24 As shown, the flow guide includes a baffle 124 and a flow guide 128, through which independent fifth and sixth flow channels are formed.

[0135] In one embodiment, the transmission part 120 is formed with a receiving portion, in which at least a portion of the rotating shaft 132, at least a portion of the mounting shaft 111, and the guide member are located. For example... Figure 27 As shown, the transmission part 120 has a receiving part, the rotating shaft 132 and the mounting shaft 111 extend into the receiving part, and the guide member is provided in the receiving part.

[0136] The guide member is located in the receiving portion of the transmission unit 120, and cooperates with the housing of the transmission unit 120 to form independent fifth flow channels 126 and sixth flow channels 127. The fifth flow channel 126 connects the first liquid inlet channel 1321 and the third liquid inlet channel 113, that is, the fifth flow channel 126 connects the first flow channel 135 and the third flow channel 115. The sixth flow channel 127 connects the second liquid inlet channel 1322 and the fourth liquid inlet channel 114, that is, the sixth flow channel 127 connects the second flow channel 136 and the fourth flow channel 116. Liquid can be supplied to the third flow channel 115 and the fourth flow channel 116 through the liquid inlets 112 of the third flow channel 115 and the fourth flow channel 116 respectively, thereby achieving the purpose of supplying liquid to the first spray nozzle 1311 and the second spray nozzle 1312.

[0137] The fifth flow channel 126 and the sixth flow channel 127 are distributed along the axial direction of the rotating shaft 132 in the receiving part. The inlet of the first flow channel 135, the outlet of the third flow channel 115, and the fifth flow channel 126 are arranged in the same layer. The inlet of the second flow channel 136, the outlet of the fourth flow channel 116, and the sixth flow channel 127 are arranged in the same layer. Since the rotating shaft 132 and the mounting shaft 111 extend into the receiving part, the fifth flow channel 126 and the sixth flow channel 127 are arranged in layers along the axial direction of the rotating shaft 132 and the mounting shaft 111. The fifth flow channel 126 and the sixth flow channel 127 surround the rotating shaft 132 and the mounting shaft 111. Therefore, during the relative rotation of the rotating shaft 132 and the mounting shaft 111, the rotating shaft 132 and the mounting shaft 111 are always connected to the fifth flow channel 126 and the sixth flow channel 127, so that the spraying part 130 can achieve continuous spraying operation during the rotation process.

[0138] It is understood that the flow guide can also be disposed on the outside of the transmission part 120, that is, the flow guide itself forms a fifth flow channel and a sixth flow channel; the flow guide is sleeved on the part of the rotating shaft 132 and the mounting shaft 111 located on the outside of the transmission part 120, that is, the inlets of the first liquid inlet channel 1321 and the second liquid inlet channel 1322 on the rotating shaft 132 and the outlets of the third liquid inlet channel 113 and the fourth liquid inlet channel 114 on the mounting shaft 111 are also matched and located on the outside of the transmission part 120 to connect the fifth flow channel and the sixth flow channel on the flow guide, and this disclosure does not limit this.

[0139] Specifically, the spray unit 130 rotates relative to the transmission unit 120 according to the logic of a Reuleaux triangle inscribed in a rounded square. Due to the geometric properties of the Reuleaux triangle, it can rotate smoothly within a square of equal width, forming a trajectory of a rounded square. Furthermore, the rotation direction of the transmission unit 120 and the spray unit 130 must be set to be opposite, and the rotational speed ratio between the transmission unit 120 and the spray unit 130 must be set to 3:1. It should be noted that the rounded square referred to here is a square-like structure with rounded corners and slightly curved straight edges.

[0140] refer to Figure 27 By making the extension length of the first spray arm 131 greater than the distance between the rotating shaft 132 of the spray section 130 and the rotating shaft of the transmission section 120, the spray area formed by the rotation of the first spray arm 131 can completely cover the rotating area of ​​the transmission section 120. The first spray arm 131 can form a roughly square spray area, avoiding the formation of empty sanitary dead corners in the spray area.

[0141] During initial configuration, the relative positions between the spray unit 130 and the transmission unit 120 need to be calibrated. By rotating the transmission unit 120 around its own axis, and with the assistance of the first drive assembly 140, when the distance between the end of the first spray arm 131 furthest from the axis 132 (hereinafter referred to as the distal end) and the axis of the transmission unit 120 is minimized, the extension direction of the first spray arm 131 towards the distal end is the same as and parallel to the direction of the axis 132 of the spray unit 130 pointing towards the axis of the transmission unit 120. This achieves the rotation of the first spray arm 131 relative to the transmission unit 120 according to the motion logic of a Reuleaux triangle inscribed in a rounded square.

[0142] Furthermore, while maintaining the rotational balance of the spray section 130, the spray section 130 may include one or more spray arms. That is, the spray section 130 may only have the first spray arm 131, or it may additionally have other spray arms with the same or similar structure as the first spray arm 131, or additionally have other spray arms with different and dissimilar structures than the first spray arm 131. These spray arms extend radially along the rotating shaft 132 together with the first spray arm 131. In other words, in addition to the first spray arm 131, the spray section 130 may additionally have other spray arms with the same or complementary functions as the first spray arm 131. These spray arms extend radially along the rotating shaft 132 together with the first spray arm 131, and rotate relative to the transmission section 120 according to the motion logic of a Reuleaux triangle inscribed in a rounded square, thereby forming a square spray area. This disclosure does not limit this.

[0143] In some embodiments, the spray arms and the first spray arm 131 are evenly spaced apart. In other embodiments, the spray arms and the first spray arm 131 are non-evenly spaced apart. "Evenly" means that any two adjacent spray arms form the same angle with the axis of rotation 132.

[0144] Those skilled in the art will understand that other spray arms (if any) of the spray unit 130 can also operate in the same manner as the first spray arm 131. However, the shape of these spray arms can be similar to that of the first spray arm 131. Figure 10 Consistent with what is shown, or can be with Figure 10 The illustrations shown are not entirely consistent, or may not be entirely consistent. In other words, while there is some indication, Figure 10 This is used to illustrate the working method of the spray arms and the first spray arm 131. Unless otherwise specified, it is not intended to limit the specific shape of the spray arms and the first spray arm 131.

[0145] In some embodiments, such as Figure 17 and Figure 18As shown, the second drive assembly 150 is connected to the transmission unit 120 and can drive the transmission unit 120 to rotate relative to the support unit 110. The second drive assembly 150 includes a drive motor (not shown), a third gear 151, and a fourth gear 152. The third gear 151 is fixed to the transmission unit 120 and coaxial with the shaft of the transmission unit 120, and the fourth gear 152 meshes with the third gear 151. The drive motor drives the fourth gear 152 to rotate, and the engagement of the fourth gear 152 with the third gear 151 drives the transmission unit 120, enabling it to rotate. The engagement of the third gear 151 and the fourth gear 152 gives the transmission unit 120 high rotational accuracy, high reliability, low maintenance cost, and long service life.

[0146] like Figure 17 and Figure 18 As shown, the second drive assembly 150 also includes a first drive shaft 153, which has a first end and a second end in opposite directions. The first end of the first drive shaft 153 is where the fourth gear 152 is mounted / connected, and the second end of the first drive shaft 153 is where the output end of the drive motor (not shown) is connected. The drive motor is used to drive the rotation of the first drive shaft 153. Connecting the drive motor and the fourth gear 152 via the rod-shaped first drive shaft 153 facilitates the layout of the drive motor and the spray unit 130 within the dishwasher 10. For example, the drive motor can be placed in a waterproof part within the dishwasher 10, while the spray unit 130 is supported in the middle of the inner tub 300.

[0147] In addition, such as Figure 17 and Figure 18 As shown, in one embodiment, in order to cooperate with the operation of the drive motor, the second end of the first transmission shaft 153 is also provided with a driven gear 154. The first transmission shaft 153 is connected to the gear on the output shaft of the drive motor through the driven gear 154, thereby realizing the power transmission to the drive motor.

[0148] It is understandable that, in addition to the transmission connection between the driven gear 154 and the fourth gear 152 via the first transmission shaft 153, the second drive assembly 150 may also include multiple connecting gears. The driven gear 154 meshes with the fourth gear 152 through these multiple connecting gears, meaning that the multiple connecting gears can replace the first transmission shaft 153 for transmission. The drive motor is configured to drive the multiple connecting gears to rotate, which in turn drives the fourth gear 152 to rotate. Connecting the drive motor and the fourth gear 152 via multiple connecting gears facilitates the layout of the drive motor and the spray unit 130 within the dishwasher 10. For example, the drive motor can be placed in a deeper, waterproof part within the dishwasher 10, while the spray unit 130 can be suspended in the middle of the inner tub 300.

[0149] It is understood that, in addition to the components described in the above embodiments, the second drive assembly 150 may also consist of a drive motor, a third synchronous pulley, a fourth synchronous pulley, and a synchronous toothed belt. The third synchronous pulley is fixed to the transmission part 120 and coaxial with the shaft of the transmission part 120. The fourth synchronous pulley is synchronously driven with the third synchronous pulley via the synchronous toothed belt. The drive motor is configured to drive the fourth synchronous pulley to rotate. The drive motor connects the third and fourth synchronous pulleys via the synchronous toothed belt to achieve meshing transmission with the driven gear 154, thereby driving the fourth gear 152. This facilitates the layout of the drive motor and the spray unit 130 within the dishwasher 10. For example, the drive motor can be placed in a deeper waterproof part within the dishwasher 10, while the spray unit 130 is suspended in the middle of the inner tub 300. Hereinafter, it will be explained by... Figure 28 and Figure 29 The possible configurations of the third gear 151 and the fourth gear 152 are described in detail.

[0150] In one embodiment, such as Figure 28 As shown, the third gear 151 and the fourth gear 152 are both bevel gears, which achieves the purpose of setting the first drive shaft 153 and the rotating shaft of the spray unit 130 perpendicularly, while having high rotational accuracy, high reliability, low maintenance cost and long service life.

[0151] In one embodiment, such as Figure 29 As shown, the third gear 151 is a crown gear and the fourth gear 152 is a cylindrical gear, so as to achieve the purpose of the first drive shaft 153 being perpendicular to the rotating shaft of the spray unit 130, while having high rotational accuracy, high reliability, low maintenance cost and long service life. Among them, the teeth of the crown gear are spur teeth or helical teeth, and the teeth on the cylindrical gear are also matched to spur teeth or helical teeth.

[0152] In one embodiment, the third gear 151 is a turbine and the fourth gear 152 is a worm gear, so as to achieve the purpose of the first drive shaft 153 being perpendicular to the rotating shaft of the spray unit 130, while having high rotational accuracy, high reliability, low maintenance cost and long service life.

[0153] In one embodiment, the transmission unit 120 and the third gear 151 are integrally formed. For example... Figure 28 and 29As shown, the third gear 151 is disposed on the shaft hole 125 of the transmission part 120. After the transmission part 120 and the support part 110 are assembled, the third gear 151 is sleeved on the mounting shaft 111 of the support part 110 to rotate coaxially with the transmission part 120. By setting it as an integral molding structure, the connection accuracy between the third gear 151 and the transmission part 120 is improved, thereby improving the driving accuracy of the transmission part 120. Of course, the transmission part 120 and the third gear 151 can be connected together by means of bonding, snap-fitting, welding, threaded connection, etc., and this disclosure does not limit this.

[0154] In addition, such as Figures 30 to 32 As shown, the cleaning module 100 also includes a third drive assembly 160, which is connected to the second drive assemblies 150 in the plurality of cleaning modules 100. The third drive assembly 160 drives the second drive assemblies 150 in the plurality of cleaning modules 100 to move, thereby driving the transmission part 120 in the plurality of cleaning modules 100 to rotate. The rotation of the spray part 130 can be actively controlled in an adjustable mode, thus allowing adjustment of the rinsing time of the corner areas of the inner drum 300 or selection of rinsing areas, improving the overall cleaning performance of the dishwasher 10. The following will be explained by... Figures 33 to 40 The possible configuration of the third drive component 160 is described in detail.

[0155] Specifically, the third drive assembly 160 includes a drive motor 161, a connector 163, and a plurality of drive gears 162. The plurality of drive gears 162 rotate synchronously through the connector 163, and the drive motor 161 is configured to drive the plurality of drive gears 162 to rotate. The plurality of drive gears 162 mesh with the driven gears 154 in the plurality of cleaning modules 100 in a one-to-one correspondence.

[0156] In one embodiment, such as Figure 33 As shown, the connector 163 is the second drive shaft 1631, and multiple drive gears 162 rotate synchronously through the second drive shaft 1631, and the drive motor 161 drives the second drive shaft 1631 to rotate.

[0157] Among them, such as Figure 34 and Figure 35 As shown, the drive motor 161 is connected to the adjacent drive gear 162 via a gear set; the drive motor 161 drives the first transmission gear 1641 to rotate, the first transmission gear 1641 meshes with the second transmission gear 1642, the second transmission gear 1642 meshes with the third transmission gear 1643, and the third transmission gear 1643 meshes with the drive gear 162. The third transmission gear 1643 has two gear rings with different numbers of teeth, so that the effect of the gearbox is achieved through the third transmission gear 1643.

[0158] Among them, such as Figure 35 and Figure 36As shown, the drive gear 162 near the drive motor 161 is provided with a gear ring that meshes with the third transmission gear 1643, a recessed gear ring that meshes with the driven gear 154, and a gear ring that meshes with the fourth transmission gear 1644 on the end of the second transmission shaft 1631. Thus, the drive gear 162 can transmit the driving force from the third transmission gear 1643 to the first transmission shaft 153, and also transmit the driving force from the third transmission gear 1643 to the second rotating shaft, so that the multiple drive gears 162 rotate synchronously. Figure 20 As shown, the driving gear 162, which is away from the drive motor 161, is provided with a recessed gear ring that engages with the driven gear 154, and also has a gear ring that meshes with the fourth transmission gear 1644 on the end of the second transmission shaft 1631. Thus, the driving force on the second transmission shaft 1631 is transmitted to the first transmission shaft 153 through the driving gear 162, so that the multiple first transmission shafts 153 rotate synchronously.

[0159] In another embodiment, such as Figure 37 As shown, the connector 163 is a second synchronous toothed belt 1632, and multiple drive gears 162 rotate synchronously through the second synchronous toothed belt 1632.

[0160] Among them, such as Figure 38 As shown, the drive motor 161 is connected to the adjacent drive gear 162 via a gear set; the drive motor 161 drives the first transmission gear 1641 to rotate, the first transmission gear 1641 meshes with the second transmission gear 1642, the second transmission gear 1642 meshes with the third transmission gear 1643, and the third transmission gear 1643 meshes with the drive gear 162. The third transmission gear 1643 has two gear rings with different numbers of teeth, so that the effect of the gearbox is achieved through the third transmission gear 1643.

[0161] The drive gear 162 closest to the drive motor 161 has a gear ring that meshes with the third transmission gear 1643, an internal gear ring that meshes with the driven gear 154, and a gear ring that meshes with the second synchronous toothed belt 1632. This allows the drive gear 162 to transmit the driving force from the third transmission gear 1643 to the first transmission shaft 153, and also to transmit the driving force from the third transmission gear 1643 to the second synchronous toothed belt 1632, thus enabling multiple drive gears 162 to rotate synchronously. The drive gear 162 furthest from the drive motor 161 has a recessed gear ring that meshes with the driven gear 154, and also a gear ring that meshes with the second synchronous toothed belt 1632. This allows the drive gear 162 to transmit the driving force from the second synchronous toothed belt 1632 to the first transmission shaft 153, thus enabling multiple first transmission shafts 153 to rotate synchronously.

[0162] In yet another embodiment, such as Figure 39As shown, the connector 163 consists of multiple second connecting gears 1633, and multiple driving gears 162 rotate synchronously through multiple second connecting gears 1633.

[0163] Among them, such as Figure 40 As shown, the drive motor 161 is connected to the adjacent drive gear 162 via a gear set; the drive motor 161 drives the first transmission gear 1641 to rotate, the first transmission gear 1641 meshes with the second transmission gear 1642, the second transmission gear 1642 meshes with the third transmission gear 1643, and the third transmission gear 1643 meshes with the drive gear 162. The third transmission gear 1643 has two gear rings with different numbers of teeth, so that the effect of the gearbox is achieved through the third transmission gear 1643.

[0164] The drive gear 162 closest to the drive motor 161 has a gear ring that meshes with the third transmission gear 1643, a recessed gear ring that meshes with the driven gear 154, and a gear ring that meshes with the second connecting gear 1633. This allows the drive gear 162 to transmit the driving force from the third transmission gear 1643 to the first transmission shaft 153, and also to transmit the driving force from the third transmission gear 1643 to multiple second connecting gears 1633, so that multiple drive gears 162 rotate synchronously. The drive gear 162 furthest from the drive motor 161 has a recessed gear ring that meshes with the driven gear 154, and a gear ring that meshes with the second connecting gear 1633. This allows the drive gear 162 to transmit the driving force from the second connecting gear 1633 to the first transmission shaft 153, so that multiple first transmission shafts 153 rotate synchronously.

[0165] To further clarify for the reader the motion logic of the Reuleaux triangle inscribed with a rounded square as described in this disclosure, the following will be combined with... Figures 41 to 49 The process of how the first spray arm 131 rotates under the drive of the transmission unit 120 according to the motion logic of a Reuleaux triangle inscribed in a rounded square is explained in detail.

[0166] like Figure 41As shown, in the X-axis and Y-axis coordinate system, Reuleaux triangle 123 has vertices 1, 2, and 3, and arcs 12, 23, and 31 as sides. The drive shaft of transmission unit 120 is located at point O, and the free end of transmission unit 120 is connected to the drive shaft 132 of spray unit 130. The drive shaft 132 of spray unit 130 is located at the center point P of Reuleaux triangle 123. The distal end of the first spray arm 131 is located at a vertex of Reuleaux triangle 123. To facilitate understanding of how the first spray arm 131 moves as an inscribed rounded square within the Reuleaux triangle under the drive of transmission unit 120, the following explanation uses the example of the distal end of the first spray arm 131 being located at vertex 1 of Reuleaux triangle 123. However, those skilled in the art will understand that the distal end of the first spray arm 131 could also be located at vertex 2 or vertex 3 of Reuleaux triangle 123.

[0167] The transmission unit 120 rotates in the opposite direction to the first spray arm 131. When the Reuleaux triangle is in... Figure 41 At the position shown, under the action of the first drive assembly 140 and the second drive assembly 150, the free end of the transmission unit 120, with its pivot (point O) as the center point, drives the pivot 132 (point P) of the spray unit 130 to rotate clockwise along the circular motion trajectory A′B′C′D′. Then, the pivot 132 (point P) of the spray unit 130 drives the distal end (vertex 1) of the first spray arm 131 to move counterclockwise around point P, starting from point A, along the rounded square motion trajectory ADGJ, wherein the first spray arm 131 is distributed along P1.

[0168] In the figure, the rounded square trajectory ADGJ formed by the rotation of the Reuleaux triangle has rounded corners. Point A is the center point of the top edge of the square, point B is the transition position between the left side of the top edge of the square and the rounded corner, point C is the transition position between the upper side of the left side of the square and the rounded corner, point D is the center point of the left side of the square, point E is the transition position between the lower side of the left side of the square and the rounded corner, point F is the transition position between the left side of the bottom edge of the square and the rounded corner, point G is the center point of the bottom edge of the square, point H is the transition position between the right side of the bottom edge of the square and the rounded corner, point I is the transition position between the lower side of the right side of the square and the rounded corner, point J is the center point of the right side of the square, point K is the transition position between the upper side of the right side of the square and the rounded corner, and point L is the transition position between the right side of the top edge of the square and the rounded corner.

[0169] When the Reuleaux triangle is in its current position, vertex 1 of the Reuleaux triangle coincides with the center point A of the top edge of the square, and α is the angle α between line segment 13 and line segment BL, which is 60°.

[0170] The transmission unit 120 rotates around point O along a circular motion trajectory A′B′C′D′. Points A′ and C′ are the two intersection points of the rotation trajectory of the transmission unit 120 (i.e., the circular motion trajectory A′B′C′D′) with the Y-axis, and points B′ and D′ are the two intersection points of the rotation trajectory of the transmission unit 120 (i.e., the circular motion trajectory A′B′C′D′) with the X-axis.

[0171] Combination Figure 42 The free end of the transmission unit 120, with its pivot (point O) as the center point, drives the pivot 132 (point P) of the spray unit 130 to rotate clockwise from point A' to point B' along a circular motion trajectory A′B′C′D′. Then, the pivot 132 (point P) of the spray unit 130 drives the distal end (vertex 1) of the first spray arm 131 to move counterclockwise from point A along a rounded square motion trajectory ADGJ towards point B, with point P as the center point. The first spray arm 131 is distributed along P1.

[0172] When the free end of the transmission unit 120 drives the rotating shaft 132 (point P) to move clockwise in the order of A'B'C'D', for example, clockwise from point A' toward point B', the far end (vertex 1) of the first spray arm 131 moves counterclockwise from point A toward point B along the edge of the rounded square motion trajectory ADGJ.

[0173] Since the first spray arm 131 is distributed along the center line P1 of the Reuleaux triangle, when the far end (vertex 1) of the first spray arm 131 moves counterclockwise from point A to point B within a square of equal width, it is a linear motion along line segment AB.

[0174] And such Figure 43 As shown, during the movement of the Reuleaux triangle, the distal end (vertex 1) of the first spray arm 131 continues to move counterclockwise to point B. The free end of the transmission unit 120 continues to drive the rotation axis 132 (point P) of the spray unit 130 clockwise to point B′, with its rotation axis (point O) as the center point. At this time, the distal end (vertex 1) of the first spray arm 131 moves from point A to point B in a near-straight line, and the angle α between line segment 13 and line segment BL changes from 60° to 30°.

[0175] It can be seen that the movement trajectory of the far end (vertex 1) of the first spray arm 131 of the spray unit 130 is on the rounded square. When the free end of the transmission unit 120 drives the rotating shaft 132 (point P) to rotate clockwise from point A' to point B', the vertex 1 of the first spray arm 131 must move from point A to point B in a straight line.

[0176] from Figures 41 to 43During the state change, the free end of the transmission unit 120 drives the rotating shaft 132 (point P) of the spray unit 130 to rotate clockwise by 90°, while the distal end (apex 1) of the first spray arm 131 rotates counterclockwise by 30°. Corresponding to this state change, the speed ratio of the distal end (apex 1) of the first spray arm 131 of the spray unit 130 is preset to -1:3. That is, when the first spray arm 131 moves counterclockwise by 30°, the transmission unit 120 rotates clockwise by 90°, and the speed ratio between the first spray arm 131 and the transmission unit 120 is -1:3.

[0177] like Figure 44 As shown, as the free end of the transmission unit 120 continues to drive the rotating shaft 132 (point P) of the spray unit 130 to move, and as the distal end (apex 1) of the first spray arm 131 of the spray unit 130 continues to rotate, the distal end (apex 1) of the first spray arm 131 continues to move counterclockwise from point B toward point C, and the free end of the transmission unit 120 continues to drive the rotating shaft 132 (point P) of the spray unit 130 to rotate clockwise from point B' toward point C'.

[0178] Since the first spray arm 131 is distributed along the center line P1 of the Reuleaux triangle, when the far end (vertex 1) of the first spray arm 131 moves counterclockwise from point B to point C within a square of equal width, it moves along the curve of the arc BC.

[0179] like Figure 45 As shown, during the continued movement of the transmission unit 120 and the first spray arm 131, the distal end (apex 1) of the first spray arm 131 moves counterclockwise from point B to point C, and the free end of the transmission unit 120 continues to drive the rotating shaft 132 (point P) of the spray unit 130 to rotate clockwise from point B′ to point C′.

[0180] When point P rotates from point B' to point C', the distal end (vertex 1) of the first spray arm 131 moves from point B to point C. At this time, line segment 13 is parallel to line segment BL, meaning the angle α between line segment 13 and line segment BL changes from 30° to 0°. Meanwhile, the free end of the transmission unit 120 continues to drive the rotating shaft 132 (point P) of the spray unit 130 to rotate by 90°.

[0181] like Figure 46 As shown, the transmission unit 120 and the first spray arm 131 continue to rotate. The free end of the transmission unit 120 continues to drive the rotating shaft 132 (point P) of the spray unit 130 to continue to move clockwise from point C' to point D'. The distal end (vertex 1) of the first spray arm 131 continues to move counterclockwise from point C to point D. When the free end of the transmission unit 120 drives the rotating shaft 132 (point P) of the spray unit 130 to move circumferentially from point C' to point D', the distal end (vertex 1) of the first spray arm 131 moves from point C to point D.

[0182] Since the first spray arm 131 is distributed along the center line P1 of the Reuleaux triangle, when the far end (vertex 1) of the first spray arm 131 moves counterclockwise from point C to point D within a square of equal width, it is a quasi-linear motion along line segment CD.

[0183] like Figure 47 As shown, the transmission unit 120 and the first spray arm 131 continue to rotate. The free end of the transmission unit 120 continues to drive the rotating shaft 132 (point P) of the spray unit 130 to continue clockwise from point C′ to point D′. The distal end (vertex 1) of the first spray arm 131 continues to move counterclockwise from point C to point D. When the free end of the transmission unit 120 drives the rotating shaft 132 (point P) of the spray unit 130 to rotate clockwise to point D′, and when point P moves from point C' to point D', the distal end (vertex 1) of the first spray arm 131 moves from point C to point D. At this time, the angle α between line segment 13 and line segment BL changes from 0° to 30°.

[0184] It can be seen that the movement trajectory of the far end (vertex 1) of the first spray arm 131 of the spray unit 130 is on the rounded square. When the free end of the transmission unit 120 drives the rotating shaft 132 (point P) of the spray unit 130 to rotate clockwise from point C' to point D', the vertex 1 of the first spray arm 131 moves clockwise from point C to point D.

[0185] When point P rotates from point C' to point D', the distal end (vertex 1) of the first spray arm 131 moves from point C to point D, at which point the angle α between line segment 13 and line segment BL changes by 30°. Correspondingly, the free end of the transmission unit 120 drives the rotating shaft 132 (point P) of the spray unit 130 to rotate by 90°. That is, when the first spray arm 131 rotates 30° counterclockwise, the transmission unit 120 rotates 90° clockwise, and the ratio of the rotational speed of the first spray arm 131 to the rotational speed of the transmission unit 120 is -1:3.

[0186] like Figure 48 As shown, the transmission unit 120 then moves clockwise, driving the distal end (vertex 1) of the first spray arm 131, i.e., the Reuleaux triangle, to continue moving counterclockwise within the rounded square. Specifically, this means that point P continues to move in a circle from point D' to point A', while the distal end (vertex 1) of the first spray arm 131 moves in a near-linear motion from point D to point E.

[0187] Since the first spray arm 131 is distributed along the center line P1 of the Reuleaux triangle, when the far end (vertex 1) of the first spray arm 131 moves counterclockwise from point D to point E within a square of equal width, it is a quasi-linear motion along line segment DE.

[0188] Specifically, when point P rotates from point D' to point A', the distal end (vertex 1) of the first spray arm 131 moves from point D to point E. When point P moves from point D' to point A', the distal end (vertex 1) of the first spray arm 131 moves from point D to point E, at which point the angle α between line segment 13 and line segment BL changes from 30° to 60°. That is, when the first spray arm 131 rotates 30° counterclockwise, the transmission unit 120 rotates 90° clockwise, and the ratio of the rotational speed of the first spray arm 131 to the rotational speed of the transmission unit 120 is -1 / 3.

[0189] Based on the rotation process of point P described above, it can be seen that when point P moves clockwise one revolution along the circular trajectory A'B'C'D', the distal end (vertex 1) of the first spray arm 131 moves from point A to point E, where vertex 2 was initially located, and the first spray arm 131 has rotated one-third of a revolution. Therefore, when the Reuleaux triangle rotates one revolution within a square with side length R, its centroid point P rotates three revolutions in the opposite direction.

[0190] The detailed process of the distal end (vertex 1) of the first spray arm 131 moving from point E to point I and from point I to point A is similar to the process of the distal end (vertex 1) of the first spray arm 131 moving from point A to point E described above. Please refer to the process of the distal end (vertex 1) of the first spray arm 131 moving from point A to point E described above. This disclosure will not repeat it here.

[0191] Furthermore, the distal end (apex 1) of the first spray arm 131 can also move clockwise, and correspondingly, the transmission unit 120 can drive the first spray arm 131 counterclockwise. Similar to the process described above where the distal end (apex 1) of the first spray arm 131 moves from point A to point E, please refer to the process described above where the distal end (apex 1) of the first spray arm 131 moves from point A to point E; this disclosure will not repeat it here.

[0192] Figure 49 This is a schematic diagram of a spray area formed by a Reuleaux triangular spray unit driven by a transmission unit, according to an embodiment of this disclosure. Figure 49 As shown, when the centroid P rotates three times in opposite directions, causing the Reuleaux triangle to rotate once within a square with side length R, a rectangular third spray area S3 is formed. Compared to the first spray area S1, the third spray area S3 better covers the corner areas of the rectangular inner liner 300, improving the cleaning effect and reducing dead corners.

[0193] It should be noted that, to improve the practicality of the technical solution, the central motion trajectory of point P is constrained to circular motion, which can be achieved through easily engineering-implemented methods such as gears, cams, or guide rails. In the described scenario, the center points A, D, G, and J of the trajectory square edge will be concave inward, thus forming a third spray area S3 with rounded corners, resembling a square.

[0194] Figure 50 This is a schematic diagram of some embodiments of this disclosure, including a second spray arm. Figure 34 As shown, in addition to the first spray arm 131, the spray section 130 may also include a second spray arm. The second spray arm can extend in the opposite direction to the first spray arm 131. The relationship between the extension length L2 of the second spray arm and the extension length L1 of the first spray arm 131 is: L1≥L2+2×L3, where L3 is the distance between the rotation axis of the spray section 130 and the rotation axis of the transmission section 120. By making the extension length L1 of the first spray arm 131 greater than the sum of the extension length L2 of the second spray arm and twice the distance L3 between the rotation axis of the spray section 130 and the rotation axis of the transmission section 120, and by ensuring that the third spray area S3 formed by the first spray arm 131 completely covers the spray area formed by the second spray arm, the second spray arm can rotate within the equal-width square formed by the first spray arm 131 as a Reuleaux triangle, without interfering with the wall 310 of the inner liner 300. The spray nozzles on the second spray arm allow for the application of more cleaning solution, thus enhancing the cleaning effect.

[0195] While the spray arms can maintain balance, the number of second spray arms can be one, two or more, and can be unequal to the number of first spray arms 131. This disclosure does not impose any restrictions on this.

[0196] The first spray arm 131 and the second spray arm can spray the same cleaning liquid, or provide different cleaning liquids through different flow channels to spray different cleaning liquids. This disclosure does not limit this.

[0197] Furthermore, the rotation of the spray section 130 is actively controlled, so the rinsing time of the corner areas of the inner drum can be adjusted or the rinsing area can be selected, thereby improving the overall cleaning performance of the dishwasher 10.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.

The scope of the invention is limited only by the appended claims.
