Technical Field

[0001] The present invention relates to the technical field of drainage structures, and particularly to an overflow exhaust structure, a water tank and a dishwasher. Background Art

[0002] With the improvement of living standards, dishwashers have gradually entered ordinary families, improving our quality of life.

[0003] Generally, the main core components of existing dishwashers usually include: an inner tank assembly, a water cup assembly, a spray arm assembly, a filter assembly, a washing pump, a drainage pump and pipelines, etc. Currently, dishwashers on the market generally perform main cleaning and tableware disinfection through high temperature (usually about 70°C), and some are also equipped with UVC ultraviolet lamp disinfection, adding silver ions to inhibit bacteria in the part materials, steam high-temperature disinfection, hot air drying, etc. Summary of the Invention

[0004] Therefore, the present invention provides an overflow exhaust structure, including:

[0005] A water and gas inlet, which is disposed through the first side of the overflow exhaust structure;

[0006] A water blocking end cover, which is disposed on the second side of the overflow exhaust structure and is arranged along the extending direction of the water and gas inlet, and is adapted to block the extending direction of the water and gas inlet; and

[0007] An overflow exhaust port, which penetrates through the overflow exhaust structure along a direction parallel to the water blocking end cover and is at least partially communicated with the water and gas inlet.

[0008] Further, it further includes: a guide rib, which at least partially surrounds the water and gas inlet and is adapted to support the water blocking end cover.

[0009] Further, at least one notch is formed on the path where the guide rib surrounds the water and gas inlet.

[0010] Further, the notch of the guide rib and the water blocking end cover jointly enclose to form the overflow exhaust port.

[0011] Further, one overflow exhaust port is provided on the overflow exhaust structure.

[0012] Further, the included angle β1 between the exhaust overflow direction S4 of the overflow exhaust port and the horizontal plane is such that 0° ≤ β1 ≤ 180°.

[0013] The water tank provided by the present invention includes:

[0014] A water tank body;

[0015] An overflow port, formed through the side wall on one side of the water tank body; and

[0016] The overflow exhaust structure as described above that communicates with the overflow port.

[0017] Furthermore, it further includes: an anti-backflow rib, arranged on the conduction path between the overflow port and the overflow exhaust port, and the anti-backflow rib is adapted to at least partially block the overflow port.

[0018] Furthermore, the anti-backflow rib is arranged at the lower edge position of the overflow port.

[0019] Furthermore, the anti-backflow rib is arranged parallel to the water-blocking end cover.

[0020] Furthermore, the lowest point position of the anti-backflow rib in the up-down direction is higher than the lowest point position of the overflow exhaust port.

[0021] The dishwasher provided by the present invention includes:

[0022] An inner container;

[0023] A spray arm, arranged inside the inner container and adapted to spray water; and

[0024] The water tank as described above, installed on the outer side of at least one side wall of the inner container.

[0025] Furthermore, an overflow port is provided on the water tank, and a through hole is provided at a position corresponding to the overflow port on the side wall of the inner container; the water tank and the inner container are communicated via the overflow exhaust structure.

[0026] Furthermore, when the water spray direction S1 of the spray arm is from right to left relative to the direction of the overflow exhaust structure, the angle between the exhaust and overflow direction S4 of the overflow exhaust port and the horizontal plane is β1, where 0° ≤ β1 ≤ 90°.

[0027] Furthermore, when the water spray direction S1 of the spray arm is from left to right relative to the direction of the overflow exhaust structure, the angle between the exhaust and overflow direction S4 of the overflow exhaust port and the horizontal plane is β1, where 90° ≤ β1 ≤ 180°.

[0028] Furthermore, a tooling rib position is also provided on the overflow exhaust structure, and the tooling rib position is adapted to adjust the orientation of the exhaust and overflow direction S4 of the overflow exhaust port.

[0029] The technical solution of the present invention has the following advantages:

[0030] 1. The overflow exhaust structure provided by the present invention is shielded by arranging a water-blocking end cover in the extending direction of the water-gas inlet, so that the liquid or gas flows along a specified path, and can prevent the liquid or gas at a specific angle from the second side of the overflow exhaust structure from directly entering the water-gas inlet in an unshielded state.

[0031] 2. The water tank provided by the present invention has the overflow port formed on the side wall of one side of the water tank, which facilitates the discharge of the excess water from the overflow port when the water level inside the water tank is too high. The overflow port is communicated with the water-gas inlet of the overflow exhaust structure, which facilitates the flow of the liquid in the water tank into the water-gas inlet of the overflow exhaust structure and discharges it from the overflow exhaust port.

[0032] 3. In the water tank provided in this embodiment, the anti-backflow rib is arranged inside the overflow port of the water tank, specifically on the conduction path between the overflow port and the overflow exhaust port, and is preferably arranged at a position corresponding to the overflow exhaust port inside the overflow port. Thus, the liquid or gas at a specific angle from the second side of the overflow exhaust structure not only has to be blocked by the water-blocking end cover, but also has to be blocked by the anti-backflow rib again after a small amount of liquid or gas enters the overflow exhaust port, reducing the situation of entering the overflow exhaust structure due to splashing.

[0033] 4. In the water tank provided by the present invention, the cooperation between the anti-backflow rib and the water-blocking end cover makes the diversion channel inside the overflow exhaust structure form a meandering structure, increasing the shielding of the liquid or gas at a specific angle from the second side of the overflow exhaust structure and improving the difficulty of the liquid or gas at a specific angle from the second side of the overflow exhaust structure entering the overflow exhaust structure.

[0034] 5. In the water tank provided in this embodiment, the lowest point position of the anti-backflow rib in the up-down direction is higher than the lowest point position of the overflow exhaust port. Thus, after the water overflowing from the water tank enters the water-gas inlet, it will be blocked by the anti-backflow rib to prevent backflow; and when the external water enters from the overflow exhaust port, it will also be blocked by the anti-backflow rib during the process of flowing towards the water tank, thereby reducing the probability of the external water entering the water tank.

[0035] 6. The dishwasher provided by the present invention conducts the water tank and the inner tank through the overflow exhaust structure, so that the water tank is located on the first side of the overflow exhaust structure, and correspondingly, the inner tank is located on the second side of the overflow exhaust structure. Thus, the liquid in the water tank flows into the water-gas inlet of the overflow exhaust structure and is discharged from the overflow exhaust port into the inner tank; while the liquid or gas at a specific angle sprayed from the inner tank is blocked by the overflow exhaust structure, reducing the situation of the water in the inner tank flowing into the water tank.

[0036] 7. The dishwasher provided by the present invention is configured such that the opening direction of the overflow exhaust port forms an angle with the jetting direction of the spray arm, and the specific value range is 90° ≤ β2 ≤ 180°, that is, the opening direction of the overflow exhaust port is set to be generally opposite to the jetting direction of the spray arm, which can reduce the entry of the water flow jetted by the spray arm into the overflow exhaust structure, and further reduce the entry of the water flow jetted by the spray arm into the water tank.

[0053] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] Embodiment 1

[0055] Combined with Figures 1 - 10 As shown, the overflow exhaust structure provided in this embodiment includes:

[0056] The water-vapor inlet b616 penetrates through and is disposed on the first side of the overflow exhaust structure.

[0057] The water-blocking end cover b614 is disposed on the second side of the overflow exhaust structure and is arranged along the extending direction of the water-vapor inlet b616, and is adapted to block the extending direction of the water-vapor inlet b616; and

[0058] The overflow exhaust port b611 penetrates through the overflow exhaust structure along a direction parallel to the water-blocking end cover b614 and is at least partially communicated with the water-vapor inlet b616.

[0059] The overflow exhaust structure is configured as an independent component, which includes a first side and a second side opposite to the first side. The water-vapor inlet b616 is disposed on the first side of the overflow exhaust structure, and the water-vapor inlet b616 at least partially penetrates through the overflow exhaust structure. The water-vapor inlet b616 is adapted to introduce liquid or gas. The water-blocking end cover b614 is disposed on the second side of the overflow exhaust structure, and the water-blocking end cover b614 is adapted to at least partially block or completely block along the extending direction of the water-vapor inlet b616. On the one hand, it redirects the liquid or gas entering the water-vapor inlet b616 from the first side of the overflow exhaust structure, and on the other hand, it prevents the liquid or gas from the second side of the overflow exhaust structure from directly entering the water-vapor inlet b616 in an unblocked state.

[0060] Preferably, in this embodiment, the liquid from the first side of the overflow exhaust structure is in a form of immersion overflow, and the liquid from the second side of the overflow exhaust structure is in a form of jet.

[0061] After the water-blocking end cover b614 blocks the extending direction of the water-vapor inlet b616, an overflow exhaust port b611 is further opened on the second side of the overflow exhaust structure. The overflow exhaust port b611 is at least partially communicated with the water-vapor inlet b616, so as to internally penetrate and communicate the overflow exhaust structure, facilitating the liquid or gas entering the water-vapor inlet b616 from the first side of the overflow exhaust structure to be discharged from the overflow exhaust port b611 located on the second side of the overflow exhaust structure.

[0062] In the specific implementation process, liquid or gas enters from the water-vapor inlet b616 on the first side of the overflow exhaust structure, passes through the internal channel of the overflow exhaust structure, and changes direction when blocked by the water-blocking end cover b614 on the second side of the overflow exhaust structure in the flow path of the liquid or gas. Finally, the liquid or gas is discharged from the overflow exhaust port b611. For the liquid or gas from the second side of the overflow exhaust structure, if it wants to enter the overflow exhaust structure, it must enter from the overflow exhaust port b611. The extending direction of the overflow exhaust port b611 is set at an angle with the extending direction of the water-vapor inlet b616. In this embodiment, the two are vertically arranged, so that the liquid or gas from the second side of the overflow exhaust structure cannot enter the overflow exhaust structure in the parallel direction of the extending direction of the water-vapor inlet b616, thereby blocking the liquid or gas at a specific angle from the second side of the overflow exhaust structure.

[0063] The overflow exhaust structure provided in this embodiment is blocked by arranging the water-blocking end cover b614 in the extending direction of the water-vapor inlet b616, so that the liquid or gas flows along the specified path, and can prevent the liquid or gas at a specific angle from the second side of the overflow exhaust structure from directly entering the water-vapor inlet b616 in an unblocked state.

[0064] Preferably, in this embodiment, the overflow exhaust structure is configured as a circular structure, at least partially penetrated on the first side along the axial direction of the overflow exhaust structure to form the water-vapor inlet b616; the second side along the axial direction of the overflow exhaust structure is blocked to form the water-blocking end cover b614. The overflow exhaust port b611 is formed along the radial direction of the overflow exhaust structure and close to the water-blocking end cover b614.

[0065] Specifically, the overflow exhaust structure further includes: a guide rib b612, at least partially surrounding the water-vapor inlet b616 and adapted to support the water-blocking end cover b614.

[0066] In this embodiment, the guide rib b612 is located on the second side of the overflow exhaust structure and protrudes from the edge of the water-vapor inlet b616. In some embodiments, the guide rib b612 surrounds the water-vapor inlet b616 for one week, and the end face of the guide rib b612 away from the water-vapor inlet b616 is adapted to support the water-blocking end cover b614.

[0067] Specifically, at least one notch is formed on the path where the guiding rib b612 surrounds the water and gas inlet b616. By forming at least one notch on the path where the guiding rib b612 surrounds the water and gas inlet b616, the connection between the notch of the guiding rib b612 and the water blocking end cover b614 can be disconnected, thus facilitating the formation of the water and gas inlet b616.

[0068] Specifically, the notch of the guiding rib b612 and the water blocking end cover b614 jointly enclose the overflow exhaust port b611.

[0069] Combined with Figure 2 As shown, the exhaust path S2 and the overflow path S3 inside the overflow exhaust structure are as shown in the figure. Both exhaust and overflow enter from the water and gas inlet b616 and finally discharge from the overflow exhaust port b611.

[0070] As a deformation, at least a part of the guiding rib b612 is arranged to surround the water and gas inlet b616 for one week, and a notch is formed in a part of the area where the guiding rib b612 surrounds the water and gas inlet b616, so that the notch of the guiding rib b612 is communicated with the overflow exhaust port b611, thereby making the overflow exhaust port b611 communicated with the water and gas inlet b616.

[0071] Specifically, one overflow exhaust port b611 is arranged on the overflow exhaust structure. In this embodiment, only one overflow exhaust port b611 is arranged on the overflow exhaust structure, so that the exhaust and overflow path of the overflow exhaust structure is fixed, which is convenient for guiding the liquid or gas entering the water and gas inlet b616 from the first side of the overflow exhaust structure and reducing the area of the liquid entering the second side of the overflow exhaust structure.

[0072] Specifically, combined with Figure 5 As shown, the included angle β1 between the exhaust and overflow direction S4 of the overflow exhaust port b611 and the horizontal plane is such that 0° ≤ β1 ≤ 180°. Preferably, 0° < β1 < 180°, so that the exhaust and overflow direction S4 of the overflow exhaust port b611 is arranged as downward as possible, which is convenient for overflow and reduces the liquid entering the second side at the same time.

[0073] Embodiment 2

[0074] Combined with Figure 1 As shown, this embodiment provides a water tank b0, including: a water tank body b9;

[0075] An overflow port b6, which penetrates through the side wall of one side of the water tank body b9; and an overflow exhaust structure as described in the above Embodiment 1 and communicated with the overflow port b6.

[0076] Preferably, the water tank b0 includes a water tank body b9 and an electrolysis device disposed inside the water tank b0. Preferably, when an electrolysis device is provided inside the water tank b0, the water tank b0 can be an electrolytic water tank, and the electrolysis device is provided inside the electrolytic water tank.

[0077] Before the water tank b0 starts to work, it is necessary to introduce water with a preset flow rate into it. When the flow meter or the switch valve fails, water will continuously flow into the water tank b0. When the water overflows the overflow port b6 on the water tank b0, the water will flow out through the overflow exhaust port b611 of the overflow exhaust structure. Preferably, an overflow alarm device is also provided on the water tank b0. When an overflow occurs in the water tank b0, the overflow alarm device reminds the user.

[0078] When the water tank b0 is working, the electrolysis device electrolyzes the brine. During the electrolysis process, gas is generated. Most of the generated gas is hydrogen, which has a low density and will move upward. The hydrogen will pass through the overflow port b6 and be discharged from the overflow exhaust port b611 of the overflow exhaust structure.

[0079] In the water tank provided in this embodiment, the overflow port b6 is formed on the side wall of one side of the water tank, which facilitates the discharge of excess water from the overflow port b6 when the water level inside the water tank is too high. The overflow port b6 is communicated with the water-gas inlet b616 of the overflow exhaust structure, which facilitates the liquid in the water tank to flow into the water-gas inlet b616 of the overflow exhaust structure and be discharged from the overflow exhaust port b611.

[0080] The overflow port b6 of the water tank is communicated with the water-gas inlet b616 of the overflow exhaust structure, that is, the overflow port b6 of the water tank is located on the first side of the overflow exhaust structure. The liquid or gas contained in the water tank is suitable to enter through the water-gas inlet b616 of the overflow exhaust structure, and after passing through the through-channel inside the overflow exhaust structure, the liquid or gas is discharged from the overflow exhaust port b611 located on the second side of the overflow exhaust structure. This enables the water in the water tank to be discharged along a specified path. At the same time, it shields the liquid or gas at a specific angle from the second side of the overflow exhaust structure, reducing the situation of external water flowing into the water tank.

[0081] Preferably, the overflow port b6 is provided at a position near the top of the water tank, so as to ensure that the water tank has a large volume and discharge the water exceeding the set volume.

[0082] Specifically, an overflow port flange b63 is circumferentially provided around the overflow port b6, and a screwing portion b617 is provided at a position corresponding to the overflow port flange b63 on the overflow exhaust structure; an internal thread or an external thread is provided on the overflow port flange b63, and a corresponding external thread or internal thread is provided on the screwing portion b617.

[0083] Through the cooperation of the overflow port flange b63 and the screwing portion b617, the overflow exhaust structure can be installed on the water tank. Preferably, the overflow port flange b63 is provided on the outside of the water tank. As a variation, the overflow port flange b63 can also be provided on the inside of the water tank or on both sides of the first water tank side wall b904 in the thickness direction. Correspondingly, the screwing portion b617 is located on the first side of the overflow exhaust structure, preferably at the circumferential position outside the water and gas inlet b616, facilitating the direct connection of the water and gas inlet b616 and the overflow port b6.

[0084] Specifically, the water tank further includes: a backflow prevention rib b62, which is provided on the conduction path between the overflow port b6 and the overflow exhaust port b611, and the backflow prevention rib b62 is adapted to at least partially block the overflow port b6.

[0085] In the water tank provided in this embodiment, the backflow prevention rib b62 is provided in the overflow port b6 of the water tank, specifically on the conduction path between the overflow port b6 and the overflow exhaust port b611, and is preferably provided at a position in the overflow port b6 corresponding to the overflow exhaust port b611. Thus, for the liquid or gas at a specific angle from the second side of the overflow exhaust structure, not only is it blocked by the water blocking end cover b614, but also after a small amount of liquid or gas enters the overflow exhaust port b611, it is blocked again by the backflow prevention rib b62, reducing the occurrence of the situation where the liquid or gas enters the overflow exhaust structure due to splashing.

[0086] Specifically, the backflow prevention rib b62 is provided at the lower edge position of the overflow port b6.

[0087] Specifically, the backflow prevention rib b62 is arranged in parallel with the water blocking end cover b614.

[0088] In the water tank provided in this embodiment, the cooperation between the backflow prevention rib b62 and the water blocking end cover b614 makes the diversion channel inside the overflow exhaust structure form a meandering structure, increasing the blockage of the liquid or gas at a specific angle from the second side of the overflow exhaust structure and improving the difficulty of the liquid or gas at a specific angle from the second side of the overflow exhaust structure entering the overflow exhaust structure.

[0089] Specifically, the lowest point position of the backflow prevention rib b62 in the up and down direction is higher than the lowest point position of the overflow exhaust port b611.

[0090] For the water tank provided in this embodiment, the lowest point of the anti-backflow rib b62 in the up-down direction is higher than the lowest point of the overflow exhaust port b611. Therefore, after the water overflowing in the water tank enters the water and gas inlet b616, it will be blocked by the anti-backflow rib b62 to avoid backflow. Moreover, when the external water enters from the overflow exhaust port b611 and flows towards the water tank, it will also be blocked by the anti-backflow rib b62, thereby reducing the probability of external water entering the water tank.

[0091] Embodiment Three

[0092] Combined with Figure 1 As shown in the figure, this embodiment provides a dishwasher, including:

[0093] Inner liner d5;

[0094] Spray arm d1, which is arranged inside the inner liner d5 and is adapted to spray water flow; and

[0095] The water tank b0 as described in the above Embodiment Two, which is installed outside the inner liner d5.

[0096] Preferably, the inner liner d5 wraps the inside of the dishwasher to form a cavity structure.

[0097] Preferably, the inner liner d5 includes an inner liner wall d51. Correspondingly, the water tank body b9 includes a first water tank side wall b904. The inner liner wall d51 is the side wall of the inner liner d5 on the side that fits the water tank body b9. Correspondingly, the first water tank side wall b904 is the side wall of the water tank body b9 on the side that fits the inner liner d5; the inner liner wall d51 is in contact with the first water tank side wall b904.

[0098] Specifically, an overflow port b6 is provided on the water tank, and a through hole is provided at a position corresponding to the overflow port b6 on the inner liner d5; the water tank b0 and the inner liner d5 are communicated via an overflow exhaust structure.

[0099] The hydrogen generated in the water tank b0 will pass through the overflow port b6 and be discharged from the overflow exhaust port b611 of the overflow exhaust structure. The hydrogen is discharged into the inner liner 5. Since the space of the inner liner 5 is large and an exhaust fan is equipped, the hydrogen is continuously discharged to the outside of the dishwasher, avoiding the occurrence of explosion hazards caused by hydrogen accumulation in a local area.

[0100] Preferably, the overflow port b6 is communicated with the through hole.

[0101] Preferably, the overflow port b6 of this embodiment is formed on the side wall b904 of the first water tank; correspondingly, the through hole is formed on the inner tank wall d51. The water tank b0 is located on the first side of the overflow exhaust structure, and correspondingly, the inner tank d5 is located on the second side of the overflow exhaust structure.

[0102] Preferably, an overflow port sealing ring b64 is further provided between the water tank b0 and the inner tank d5, and the overflow port sealing ring b64 surrounds the overflow port b6.

[0103] The dishwasher provided in this embodiment conducts the water tank b0 and the inner tank d5 through the overflow exhaust structure, so that the water tank b0 is located on the first side of the overflow exhaust structure, and correspondingly, the inner tank d5 is located on the second side of the overflow exhaust structure, so that the liquid in the water tank b0 flows in from the water-gas inlet b616 of the overflow exhaust structure and is discharged into the inner tank d5 from the overflow exhaust port b611; while the liquid or gas at a specific angle sprayed from the inner tank d5 is blocked by the overflow exhaust structure, reducing the situation where the water in the inner tank d5 flows into the water tank b0.

[0104] Specifically, when the water flow spraying direction S1 of the spray arm d1 is from right to left relative to the direction of the overflow exhaust structure, the included angle between the exhaust overflow direction S4 of the overflow exhaust port b611 and the horizontal plane is β1, where 0° ≤ β1 ≤ 90°.

[0105] Specifically, when the water flow spraying direction S1 of the spray arm d1 is from left to right relative to the direction of the overflow exhaust structure, the included angle between the exhaust overflow direction S4 of the overflow exhaust port b611 and the horizontal plane is β1, where 90° ≤ β1 ≤ 180°.

[0106] During the normal use of the dishwasher, the spray arm d1 of the dishwasher rotates driven by water, and the rotation mode can be clockwise or counterclockwise. For the sake of simplicity of description, here, with reference to the jet direction of the water flow relative to the overflow and exhaust structure in the front view state of the overflow and exhaust structure, the arrangement angle of the overflow and exhaust port b611 of the overflow and exhaust structure is recorded. When the water jet direction S1 of the spray arm d1 is from right to left relative to the direction of the overflow and exhaust structure, the included angle between the exhaust and overflow direction S4 of the overflow and exhaust port b611 and the horizontal plane is β1, where 0° ≤ β1 ≤ 90°, preferably 0° < β1 < 90°, and the best range is 30° < β1 < 60°. When the water jet direction S1 of the spray arm d1 is from left to right relative to the direction of the overflow and exhaust structure, the included angle between the exhaust and overflow direction S4 of the overflow and exhaust port b611 and the horizontal plane is β1, where 90° ≤ β1 ≤ 180°, preferably 90° < β1 < 180°, and the best range is 120° < β1 < 150°.

[0107] Preferably, a steam generating device or a liquid heating device is further provided in the dishwasher. During the washing operation of the dishwasher, high-temperature water vapor is generated inside. The high-temperature water vapor will enter the exhaust and overflow device through the overflow and exhaust port b611. Since a reflux prevention rib b62 is also provided on the conduction path between the overflow port b6 and the overflow and exhaust port b611, most of the water vapor is blocked outside by the reflux prevention rib b62, and after condensation, it flows into the inner tank from the overflow and exhaust port b611 under the action of gravity. In addition, during the flushing process, the water sprayed by the spray arm will also splash into the exhaust and overflow device. Due to the presence of the reflux prevention rib b62, very little water will enter the water tank, and it will not affect the electrolysis effect or the washing effect.

[0108] As a variation, the value range of the included angle β2 between the exhaust and overflow direction S4 of the overflow and exhaust port b611 and the water jet direction S1 of the spray arm d1 is 90° ≤ β2 ≤ 180°.

[0109] Preferably, at least a part of the spray arm d1 is arranged inside the inner tank d5. In this embodiment, the spray arm d1 is located in the middle of the inner tank d5, and the water tank b0 is installed on the side wall of the inner tank d5, so that the overflow and exhaust structure is also located on the side wall of the water tank b0. The spray arm d1 sprays water by rotating, and the water jet direction S1 is as shown in the figure. In this embodiment, the spray arm d1 rotates clockwise as an example, that is, the high-pressure water column sprayed by the spray arm d1 is washed in the counterclockwise direction. At this time, setting the opening direction of the overflow and exhaust port b611 in a direction substantially opposite to the spraying direction of the spray arm d1 can reduce the entry of the water flow sprayed by the spray arm d1 into the overflow and exhaust structure, and further reduce the entry of the water flow sprayed by the spray arm d1 into the water tank b0.

[0110] For the dishwasher provided in this embodiment, by setting the opening direction of the overflow exhaust port b611 at an angle to the jet direction of the spray arm d1, specifically, the value range is 90° ≤ β2 ≤ 180°, that is, the opening direction of the overflow exhaust port b611 is set in a direction substantially opposite to the jet direction of the spray arm d1, which can reduce the entry of the water jet from the spray arm d1 into the overflow exhaust structure, and further reduce the entry of the water jet from the spray arm d1 into the water tank b0.

[0111] Specifically, a tooling rib b615 is further provided on the overflow exhaust structure, and the tooling rib b615 is adapted to adjust the orientation of the exhaust overflow direction S4 of the overflow exhaust port b611.

[0112] Preferably, the tooling rib b615 is arranged on the outer edge of the guide rib b612. By rotating the tooling rib b615, the orientation of the overflow exhaust port b611 can be adjusted, so as to conveniently set the opening direction of the overflow exhaust port b611 reasonably according to the jet direction of the spray arm d1, and reduce the entry of the water jet from the spray arm d1 into the water tank b0.

[0113] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
