[0034] Further, when the water spraying direction S1 of the spray arm 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 exhaust port and the horizontal plane is β1, where 90° ≤ β1 ≤ 180°.

[0035] The technical solution of the present invention has the following advantages:

[0036] 1. The overflow and exhaust structure provided by the present invention forms an overflow path by internally communicating at least part of the overflow exhaust port with the water and gas inlet; and at the same time, the exhaust inlet through hole is adapted to internally communicate at least part of the water and gas inlet with the exhaust cavity, thereby forming an exhaust path between the water and gas inlet and the exhaust cavity, so that the overflow and exhaust structure can both overflow and exhaust, and the exhaust path and the overflow path are separated from each other, so that exhaust and overflow do not interfere with each other, facilitating separation.

[0037] 2. The overflow and exhaust structure provided by the present invention is provided with at least one exhaust and drainage notch on the water retaining cover, thereby communicating the exhaust cavity with the outside, so as to facilitate the discharge of the gas or liquid entering the exhaust cavity to the outside of the overflow and exhaust structure.

[0038] 3. The overflow and exhaust structure provided by the present invention, the exhaust cavity through hole penetrates the water retaining cover along a first direction, and the exhaust and drainage notch penetrates the water retaining cover along a direction perpendicular to the first direction, so that the exhaust cavity through hole and the exhaust and drainage notch are in a non-parallel state, preventing the liquid from the outside of the overflow and exhaust structure from directly communicating with the exhaust cavity through hole through the exhaust and drainage notch, thereby reducing the probability of the liquid from the outside of the overflow and exhaust structure entering the water and gas inlet.

[0039] 4. The overflow exhaust structure provided by the present invention, the conduction path between the exhaust cavity and the water-gas inlet is only conducted through the exhaust cavity through-hole and the exhaust inlet through-hole, thereby reducing the opening area in the exhaust cavity and reducing the occurrence of gas or liquid in the exhaust cavity entering the water-gas inlet from the exhaust cavity through-hole.

[0040] 5. The overflow exhaust structure provided by this embodiment 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 the specified path, and can prevent 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.

[0041] 6. 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 excess water to be discharged 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 liquid in the water tank to flow into the water-gas inlet of the overflow exhaust structure and be discharged from the overflow exhaust port.

[0042] 7. The water tank provided by the present invention, the anti-backflow rib is arranged in the overflow port of the water tank, specifically arranged on the conduction path between the overflow port and the overflow exhaust port, and preferably arranged at a position corresponding to the overflow exhaust port inside the overflow port. Thus, 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 occurrence of liquid or gas entering the overflow exhaust structure due to splashing.

[0043] 8. The cooperation between the anti-backflow rib and the water-blocking end cover of the water tank provided by the present invention makes the diversion channel inside the overflow exhaust structure form a meandering structure, increasing the shielding of liquid or gas at a specific angle from the second side of the overflow exhaust structure and improving the difficulty of liquid or gas at a specific angle from the second side of the overflow exhaust structure entering the overflow exhaust structure.

[0044] 9. 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, so that 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 occurrence of water in the inner tank flowing into the water tank.

[0062] Embodiment 1

[0063] Combined with Figures 1 - 5 As shown, the overflow exhaust structure provided in this embodiment includes:

[0064] Water vapor enters the side wall b67, is arranged in a circle, and penetrates through the first side of the overflow exhaust structure along the inside.

[0065] The water vapor inlet b616 is formed by the surrounding of the water vapor entering side wall b67 and is conducted in the first direction.

[0066] The overflow exhaust port b611 is arranged at an angle to the first direction and penetrates through the water vapor entering side wall b67, and at least part of the inside of the overflow exhaust port b611 is conductively connected to the water vapor inlet b616.

[0067] The water baffle housing b65 is arranged around the outside of the water vapor entering side wall b67, and an exhaust cavity b66 is formed between the water baffle housing b65 and the water vapor entering side wall b67.

[0068] The exhaust inlet through hole b671 is arranged at an angle to the first direction and penetrates through the water vapor entering side wall b67, and the exhaust inlet through hole b671 is adapted to conduct at least part of the inside of the water vapor inlet b616 to the exhaust cavity b66.

[0069] In the overflow exhaust structure provided in this embodiment, by conductively connecting at least part of the inside of the overflow exhaust port b611 to the water vapor inlet b616, an overflow path is formed; and at the same time, the exhaust inlet through hole b671 is adapted to conduct at least part of the inside of the water vapor inlet b616 to the exhaust cavity b66, so as to form an exhaust path between the water vapor inlet b616 and the exhaust cavity b66, enabling the overflow exhaust structure to overflow and exhaust at the same time, and the exhaust path and the overflow path are separated from each other, so that exhaust and overflow do not interfere with each other, facilitating separation.

[0070] In the specific use process, when the liquid enters the overflow exhaust structure from the water vapor inlet b616, it can be discharged from the overflow exhaust port b611. When the gas enters the overflow exhaust structure from the water vapor inlet b616, it can escape into the exhaust cavity b66 through the exhaust inlet through hole b671; while for the liquid or gas from outside the overflow exhaust structure, due to the relatively tortuous arrangement of the exhaust path and the overflow path, it cannot easily enter the inside of the water vapor inlet b616.

[0071] Specifically, at least one exhaust and drainage notch b651 is provided on the water baffle housing b65, and the exhaust and drainage notch b651 is adapted to conduct the exhaust cavity b66 to the outside.

[0072] In the overflow exhaust structure provided in this embodiment, by providing at least one exhaust and drainage notch b651 on the water baffle housing b65, the exhaust cavity b66 is conducted to the outside, so as to facilitate the discharge of the gas or liquid entering the exhaust cavity b66 to the outside of the overflow exhaust structure.

[0073] Preferably, three exhaust and drainage notches b651 are provided on the water baffle housing b65. By providing a plurality of exhaust and drainage notches b651, the gas dissipation efficiency is increased. And preferably, in the use state, at least one of the exhaust and drainage notches b651 is provided at the lowest point of the overflow exhaust structure along the gravity direction, so as to facilitate discharging all the gas or liquid in the exhaust cavity b66 to the outside of the overflow exhaust structure to avoid residue.

[0074] Specifically, the exhaust and drainage notch b651 is provided in the edge area of the water baffle housing b65. Thus, when the overflow exhaust structure is in the installed state, the water baffle housing b65 can be in a state of being attached to the wall surface, so that the area defined between the exhaust and drainage notch b651 and the wall surface is a through area.

[0075] Specifically, the exhaust and drainage notch b651 penetrates the water baffle housing b65 along a direction perpendicular to the first direction.

[0076] Specifically, an exhaust cavity through hole b661 is provided on the water baffle housing b65. The exhaust cavity through hole b661 penetrates the water baffle housing b65 along the first direction, and enables the water and gas inlet b616 and the exhaust cavity b66 to be at least partially internally conducted via the exhaust inlet through hole b671.

[0077] For the overflow exhaust structure provided in this embodiment, the exhaust cavity through hole b661 penetrates the water baffle housing b65 along the first direction, and the exhaust and drainage notch b651 penetrates the water baffle housing b65 along a direction perpendicular to the first direction, so that the exhaust cavity through hole b661 and the exhaust and drainage notch b651 are in a non-parallel state, avoiding the liquid from the outside of the overflow exhaust structure directly conducting with the exhaust cavity through hole b661 through the exhaust and drainage notch b651, thereby reducing the probability of the liquid from the outside of the overflow exhaust structure entering the water and gas inlet b616.

[0078] For the overflow exhaust structure provided in this embodiment, the conduction path between the exhaust cavity b66 and the water and gas inlet b616 is only conducted through the exhaust cavity through hole b661 and the exhaust inlet through hole b671, thereby reducing the opening area in the exhaust cavity b66 and reducing the occurrence of the gas or liquid in the exhaust cavity b66 entering the water and gas inlet b616 through the exhaust cavity through hole b661.

[0079] Specifically, it further includes:

[0080] The water-blocking end cover b614 is arranged on the second side of the overflow and exhaust structure and is arranged along the extending direction of the water and gas inlet b616, and is adapted to block the extending direction of the water and gas inlet b616.

[0081] The overflow and exhaust structure is configured as an independent component, which includes a first side and a second side opposite to the first side. The water and gas inlet b616 is arranged on the first side of the overflow and exhaust structure. The water and gas inlet b616 at least partially penetrates the overflow and exhaust structure. The water and gas inlet b616 is adapted to introduce liquid or gas. The water-blocking end cover b614 is arranged on the second side of the overflow and exhaust structure. The water-blocking end cover b614 is adapted to at least partially block or completely block along the extending direction of the water and gas inlet b616. On the one hand, it redirects the liquid or gas entering the water and gas inlet b616 from the first side of the overflow and exhaust structure. On the other hand, it prevents the liquid or gas from the second side of the overflow and exhaust structure from directly entering the water and gas inlet b616 in an unblocked state.

[0082] Preferably, in this embodiment, the liquid from the first side of the overflow and exhaust structure is a submerged overflow, and the liquid from the second side of the overflow and exhaust structure is a jet type.

[0083] After the water-blocking end cover b614 blocks the extending direction of the water and gas inlet b616, an overflow and exhaust port b611 is further opened on the second side of the overflow and exhaust structure. The overflow and exhaust port b611 is at least partially communicated with the water and gas inlet b616, so as to internally penetrate and communicate the overflow and exhaust structure, facilitating the liquid or gas entering the water and gas inlet b616 from the first side of the overflow and exhaust structure to be discharged from the overflow and exhaust port b611 located on the second side of the overflow and exhaust structure.

[0084] In the specific implementation process, the liquid or gas enters from the water and gas inlet b616 on the first side of the overflow and exhaust structure, passes through the internal channel of the overflow and exhaust structure, and is blocked and redirected by the water-blocking end cover b614 located on the second side of the overflow and exhaust structure on the flow path of the liquid or gas. Finally, the liquid or gas is discharged from the overflow and exhaust port b611. And for the liquid or gas from the second side of the overflow and exhaust structure, if it wants to enter the overflow and exhaust structure, it must enter from the overflow and exhaust port b611. The extending direction of the overflow and exhaust port b611 is arranged at an angle with the extending direction of the water and gas inlet b616. In this embodiment, the two are perpendicularly arranged, so that the liquid or gas from the second side of the overflow and exhaust structure cannot enter the overflow and exhaust structure from the parallel direction of the extending direction of the water and gas inlet b616, thereby blocking the liquid or gas at a specific angle from the second side of the overflow and exhaust structure.

[0085] The overflow exhaust structure provided in this embodiment is shielded by arranging a water-blocking end cover b614 in the extending direction of the water-gas inlet b616, so that the liquid or gas flows along a specified path, and it 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 b616 in an unshielded state.

[0086] Preferably, in this embodiment, the overflow exhaust structure is configured as a circular structure, at least partially penetrated on the first side along the axis direction of the overflow exhaust structure to form the water-gas inlet b616; the second side along the axis direction of the overflow exhaust structure is blocked to form the water-blocking end cover b614. An overflow exhaust port b611 is formed along the radial direction of the overflow exhaust structure and close to the water-blocking end cover b614.

[0087] Specifically, the water-blocking end cover b614 is at least partially joined to the side wall of the water-gas inlet b67.

[0088] Specifically, it further includes: a guide rib b612, which is at least partially arranged around the water-gas inlet b616 and is adapted to support the water-blocking end cover b614.

[0089] 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-gas inlet b616. In some embodiments, the guide rib b612 is arranged around the water-gas inlet b616 for one week, and the end face of the guide rib b612 away from the water-gas inlet b616 is adapted to support the water-blocking end cover b614.

[0090] Specifically, at least one notch is formed on the path where the guide rib b612 surrounds the water-gas inlet b616. By forming at least one notch on the path where the guide rib b612 surrounds the water-gas inlet b616, the connection between the notch of the guide rib b612 and the water-blocking end cover b614 can be disconnected, so as to facilitate the formation of the water-gas inlet b616.

[0091] Specifically, the notch of the guide rib b612, the water-blocking end cover b614 and the outer side wall of the water-blocking cover b65 jointly enclose the overflow exhaust port b611. Thus, the overflow exhaust port b611 is in a shielded state, increasing the tortuosity of the overflow exhaust port b611, and preventing the liquid or gas from the second side of the overflow exhaust structure from directly entering the water-gas inlet b616 in an unshielded state.

[0092] In this embodiment, only one overflow exhaust port b611 is provided on the overflow exhaust structure, so that the overflow path of the overflow exhaust structure is fixed, facilitating the guiding of the liquid or gas entering the water-gas inlet b616 from the first side of the overflow exhaust structure, and reducing the area where liquid enters from the second side of the overflow exhaust structure. At the same time, only one exhaust inlet through hole b671 is provided on the overflow exhaust structure, so as to reduce the probability of liquid from the outside of the overflow exhaust structure entering the water-gas inlet b616 while ensuring exhaust.

[0093] Specifically, the angle between the exhaust overflow direction S4 of the overflow exhaust port b611 and the horizontal plane is β1, where 0° ≤ β1 ≤ 180°. Preferably, 0° < β1 < 180°, so that the exhaust overflow direction S4 of the overflow exhaust port b611 is arranged as downward as possible, facilitating overflow and reducing the entry of liquid on the second side.

[0094] Embodiment Two

[0095] Combined with Figures 6 - 8 As shown, this embodiment provides a water tank b0, including: a water tank body b9;

[0096] 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 Embodiment One above that is communicated with the overflow port b6.

[0097] Preferably, the water tank b0 includes a water tank body b9 and an electrolysis device provided 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 an electrolysis device is provided inside the electrolytic water tank.

[0098] Before the water tank b0 starts to work, a preset flow rate of water needs to be introduced 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, which gives a reminder to the user when the water tank b0 overflows.

[0099] 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.

[0100] The water tank provided in this embodiment has an overflow port b6 formed on the side wall of one side thereof, facilitating 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 in communication with the water-gas inlet b616 of the overflow exhaust structure, facilitating the inflow of the liquid in the water tank from the water-gas inlet b616 of the overflow exhaust structure and discharging it from the overflow exhaust port b611.

[0101] The overflow port b6 of the water tank is in communication 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, and the liquid or gas contained in the water tank is adapted to enter from 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.

[0102] Preferably, the overflow port b6 is provided at a position near the top of the water tank, thereby ensuring that the water tank has a large volume and discharging the water exceeding the set volume.

[0103] Specifically, the water tank further includes: an anti-backflow rib b62, which is provided on the conduction path between the overflow port b6 and the overflow exhaust port b611, and the anti-backflow rib b62 is adapted to at least partially shield the overflow port b6.

[0104] In the water tank provided in this embodiment, the anti-backflow rib b62 is provided inside 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 inside the overflow port b6 corresponding to the overflow exhaust port b611. Thus, the liquid or gas at a specific angle from the second side of the overflow exhaust structure not only has to be shielded by the water-blocking end cover b614, but also has to be blocked again by the anti-backflow rib b62 after a small amount of liquid or gas enters the overflow exhaust port b611, reducing the situation of entering the overflow exhaust structure due to splashing.

[0105] Specifically, the anti-backflow rib b62 is provided at the lower edge position of the overflow port b6.

[0106] Specifically, the anti-backflow rib b62 is arranged in parallel with the water-blocking end cover b614.

[0107] In the water tank provided in this embodiment, the cooperation between the anti-backflow rib b62 and the water-blocking end cover b614 forms a curved structure in the diversion channel inside the overflow and exhaust structure, increasing the shielding of liquid or gas at a specific angle from the second side of the overflow and exhaust structure, and making it more difficult for liquid or gas at a specific angle from the second side of the overflow and exhaust structure to enter the overflow and exhaust structure.

[0108] Specifically, the lowest point position of the anti-backflow rib b62 in the up-down direction is higher than the lowest point position of the overflow exhaust port b611.

[0109] In the water tank provided in this embodiment, the lowest point position of the anti-backflow rib b62 in the up-down direction is higher than the lowest point position 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; and 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.

[0110] Embodiment Three

[0111] Combined with Figures 9 - 10 As shown, this embodiment provides a dishwasher, including:

[0112] Inner container d5;

[0113] Spray arm d1, which is arranged inside the inner container d5 and is suitable for spraying water flow; and

[0114] The water tank as described in Embodiment 2 above, which is installed on the outer side of at least one side wall of the inner container d5.

[0115] Preferably, the inner container d5 wraps the inside of the dishwasher to form a cavity structure.

[0116] Preferably, the inner container d5 includes an inner container wall d51. Correspondingly, the water tank body b9 includes a first water tank side wall b904. The inner container wall d51 is the side wall of the inner container 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 container d5; the inner container wall d51 is in contact with the first water tank side wall b904.

[0117] 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 side wall of the inner container d5; the water tank and the inner container d5 are communicated via an overflow and exhaust structure.

[0118] 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 tank 5. Since the space of the inner tank 5 is large and an exhaust fan is equipped, the hydrogen is continuously discharged to the outside of the dishwasher, avoiding the explosion hazard caused by hydrogen accumulation in a local area.

[0119] Preferably, the overflow port b6 is communicated with the through hole.

[0120] 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.

[0121] Preferably, an overflow port sealing ring b64 is further arranged between the water tank b0 and the inner tank d5, and the overflow port sealing ring b64 is arranged around the overflow port b6.

[0122] 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. Thus, the liquid in the water tank b0 flows in from the water and gas inlet b616 of the overflow exhaust structure and is discharged from the overflow exhaust port b611 into the inner tank d5; 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 that the water in the inner tank d5 flows into the water tank b0.

[0123] 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 and overflow direction S4 of the overflow exhaust port b611 and the horizontal plane is β1, where 0° ≤ β1 ≤ 90°.

[0124] 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 and overflow direction S4 of the overflow exhaust port b611 and the horizontal plane is β1, where 90° ≤ β1 ≤ 180°.

[0125] During the normal use of the dishwasher, the spray arm d1 of the dishwasher will rotate driven by water, and the rotation direction can be clockwise or counterclockwise. For 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 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 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°.

[0126] Preferably, a steam generating device or a liquid heating device is further provided inside the dishwasher. During the washing operation of the dishwasher, high-temperature water vapor will be generated inside. The high-temperature water vapor will enter the exhaust and overflow device through the overflow and exhaust port b611. Since an anti-backflow 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 anti-backflow rib b62 and then flows into the inner tank from the overflow and exhaust port b611 under the action of gravity after condensation. 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 anti-backflow rib b62, very little water will enter the water tank and will not affect the electrolysis effect or the washing effect.

[0127] As a variant, the value range of the 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°.

[0128] Preferably, at least 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 roughly opposite to the jet direction of the spray arm d1 can reduce the entry of the water jet from the spray arm d1 into the overflow and exhaust structure, and further reduce the entry of the water jet from the spray arm d1 into the water tank b0.

[0129] The dishwasher provided in this embodiment is configured such that the opening direction of the overflow exhaust port b611 forms an angle with the jetting direction of the spray arm d1, and the specific value range is 90° ≤ β2 ≤ 180°, that is, the opening direction of the overflow exhaust port b611 and the jetting direction of the spray arm d1 are set to be in substantially opposite directions, which can reduce the entry of the water flow jetted by the spray arm d1 into the overflow exhaust structure, and further reduce the entry of the water flow jetted by the spray arm d1 into the water tank b0.

[0130] 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 alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of the present invention.
