[0010] Furthermore, the water retaining rib is arranged at the upper edge of the water vapor inlet.

[0011] Furthermore, the water vapor inlet and the overflow exhaust port are connected via a conducting hole.

[0012] Furthermore, the overflow exhaust port is arranged perpendicular to the first direction and penetrates the overflow exhaust structure.

[0013] Furthermore, the overflow exhaust ports include at least two, and two adjacent overflow exhaust ports are spaced apart by a partition boss.

[0014] Furthermore, the overflow exhaust structure at least includes an upper overflow exhaust port opening upward, and a lower overflow exhaust port opening downward.

[0015] The water tank provided by the present invention includes: a water tank body;

[0016] An overflow port is formed by penetrating the side wall of one side of the water tank body; and the overflow exhaust structure as described above is communicated with the overflow port.

[0017] Furthermore, an overflow port flange is arranged around the overflow port, and a screw-on portion is arranged on the overflow exhaust structure at a position corresponding to the overflow port flange; an internal thread or an external thread is arranged on the overflow port flange, and an external thread or an internal thread is arranged correspondingly on the screw-on portion.

[0018] Furthermore, an anti-backflow rib is provided at the lower edge of the overflow port, and the anti-backflow rib is suitable for at least partially shielding the overflow port.

[0019] Furthermore, when the overflow exhaust structure and the water tank body are assembled, the backflow prevention ribs and the water retaining ribs are arranged at intervals in the horizontal direction and staggered in the up-down direction.

[0020] Furthermore, the anti-backflow ribs are arranged in parallel with the water retaining ribs.

[0021] Furthermore, when the overflow exhaust structure and the water tank body are assembled, at least a portion of the screw-on portion abuts against the anti-backflow rib.

[0022] Furthermore, the lowest point of the anti-backflow rib in the up-down direction is higher than the lowest point of the conducting hole inside the overflow exhaust structure.

[0023] The dishwasher provided by the present invention comprises:

[0024] Liner; and

[0025] A water tank as described above is installed outside the inner tank.

[0026] Furthermore, the water tank is provided with an overflow port, and the inner tank is provided with a through hole at a position corresponding to the overflow port; the water tank and the inner tank are connected via an overflow exhaust structure.

[0027] Furthermore, an overflow port sealing ring is provided between the water tank and the inner tank, and the overflow port sealing ring is provided around the overflow port.

[0028] The technical solution of the present invention has the following advantages:

[0029] 1. The overflow exhaust structure provided by the present invention cooperates with the overflow exhaust port through a water retaining rib, and the overflow exhaust port is arranged at an angle to the first direction, so that when the liquid or gas from the second side of the overflow exhaust structure enters from the overflow exhaust port, its entry direction is also at an angle to the first direction, and under the shielding effect of the water retaining rib, the probability of the liquid or gas from the second side of the overflow exhaust structure being able to directly enter the water vapor inlet is reduced, thereby improving the single-sided overflow exhaust characteristics of the overflow exhaust structure.

[0030] 2. The overflow exhaust structure provided by the present invention provides a water-blocking end cover in the extension direction of the water vapor inlet for shielding, so that the liquid or gas flows along a prescribed 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 in an unobstructed state.

[0031] 3. The overflow exhaust structure provided by the present invention has an overflow exhaust port that passes through the overflow exhaust structure perpendicular to the first direction, so that the guide channel inside the overflow exhaust structure forms a T-shaped structure, so that when liquid or gas enters the second side of the overflow exhaust structure, it can move or drip in a direction perpendicular to the first direction, thereby reducing the situation where liquid or gas from the second side of the overflow exhaust structure enters the overflow exhaust structure.

[0032] 4. The water tank provided by the present invention has an overflow port formed on one side wall of the water tank, so that when the water level inside the water tank is too high, excess water can be discharged from the overflow port. The overflow port is in communication with the water vapor inlet of the overflow and exhaust structure, so that the liquid in the water tank can flow into the water vapor inlet of the overflow and exhaust structure and be discharged from the overflow and exhaust port.

[0033] 5. The water tank provided in this embodiment is provided with anti-backflow ribs, and the lowest point of the anti-backflow ribs in the up and down direction is higher than the lowest point of the conducting hole inside the overflow exhaust structure. Therefore, after the water overflowing from the water tank enters the water vapor inlet, it will be blocked by the anti-backflow ribs to prevent backflow; and after the external water enters from the overflow exhaust port, it will also be blocked by the anti-backflow ribs in the process of flowing into the water tank, thereby reducing the probability of external water entering the water tank.

[0034] 6. The water tank provided in this embodiment has the anti-backflow ribs and the water retaining ribs staggered in the up and down directions, so that the water flow path becomes a broken line. On the one hand, the external water flow can be blocked multiple times when flowing into the water tank, and on the other hand, it does not affect the discharge of liquid inside the water tank.

[0035] 7. The dishwasher provided in this embodiment connects the water tank and the inner tank through an overflow exhaust structure, so that the water tank is located on a first side of the overflow exhaust structure, and correspondingly, the inner tank is located on a second side of the overflow exhaust structure, so that the liquid in the water tank flows into the water vapor inlet of the overflow exhaust structure and is discharged into the inner tank from the overflow exhaust port; and the liquid sprayed from the inner tank at a specific angle is blocked by the overflow exhaust structure, thereby reducing the occurrence of water in the inner tank flowing into the water tank.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0051] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] Example 1

[0053] Combine Figure 1-Figure 7 As shown, the overflow exhaust structure b61 provided in this embodiment includes:

[0054] The water vapor inlet b616 is provided along the first direction and penetrates the overflow exhaust structure b61;

[0055] at least one overflow exhaust port b611, which is angled with the first direction and penetrates the overflow exhaust structure, and the overflow exhaust port b611 is at least partially connected to the interior of the water vapor inlet b616; and

[0056] The water retaining rib b613 is disposed inside the water vapor inlet b616 and at least partially blocks the water vapor inlet b616 along the first direction.

[0057] The overflow exhaust structure is constructed as an independent component, which includes a first side and a second side arranged opposite to the first side. The first side of the overflow exhaust structure is provided with a water vapor inlet b616, and the water vapor inlet b616 is arranged to penetrate the overflow exhaust structure along a first direction; the water vapor inlet b616 is suitable for passing liquid or gas.

[0058] An overflow exhaust port b611 is also provided on the second side of the overflow exhaust structure, and the overflow exhaust port b611 is at least partially internally connected to the water vapor inlet b616, thereby internally penetrating the overflow exhaust structure, making it convenient for 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.

[0059] The overflow exhaust port b611 is angled with the first direction and passes through the overflow exhaust structure, so that the liquid or gas entering the water vapor inlet port b616 from the first side of the overflow exhaust structure is redirected through the overflow exhaust structure.

[0060] A water retaining rib b613 is also provided inside the water vapor inlet b616, and the water retaining rib b613 at least partially blocks the water vapor inlet b616 along the first direction. The water retaining rib b613 is provided on the conducting path between the water vapor inlet b616 and the overflow exhaust port b611, and plays a shielding role on the water vapor inlet b616. On the one hand, the liquid or gas entering the water vapor inlet b616 from the first side of the overflow exhaust structure can be discharged smoothly. On the other hand, the liquid or gas from the second side of the overflow exhaust structure can be blocked by the water retaining rib b613 when entering from the overflow exhaust port b611, thereby avoiding directly entering the water vapor inlet b616.

[0061] The overflow exhaust structure provided in this embodiment is coordinated with the overflow exhaust port b611 through the water retaining rib b613, and the overflow exhaust port b611 is set at an angle to the first direction, so that when the liquid or gas from the second side of the overflow exhaust structure enters from the overflow exhaust port b611, its entry direction is also at an angle to the first direction, and under the shielding effect of the water retaining rib b613, the probability of the liquid or gas from the second side of the overflow exhaust structure being able to directly enter the water vapor inlet b616 is reduced, thereby improving the single-sided overflow exhaust characteristics of the overflow exhaust structure.

[0062] Specifically, the overflow exhaust structure further includes:

[0063] The water-blocking end cover b614 is arranged away from the open end of the water vapor inlet b616 and is suitable for blocking the water vapor inlet b616 extending along the first direction.

[0064] The water retaining end cover b614 is also arranged on the second side of the overflow exhaust structure. The water retaining end cover b614 is suitable for at least partially blocking or completely blocking the water vapor inlet b616 extending along the first direction. 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 unobstructed state.

[0065] Preferably, in this embodiment, the liquid from the first side of the overflow and exhaust structure overflows in a diffuse manner, and the liquid from the second side of the overflow and exhaust structure overflows in a jet manner. The diffuse manner is a state in which the liquid level naturally rises and overflows at a certain height, and the jet manner is a state in which the water flow is sprayed by a structure such as a nozzle or a spray arm.

[0066] In a 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 is blocked by the water retaining end cap b614 on the second side of the overflow exhaust structure on the flow path of the liquid or gas, causing the flow to change direction, and finally the liquid or gas is discharged from the overflow exhaust port b611. If the liquid or gas from the second side of the overflow exhaust structure wants to enter the overflow exhaust structure, it must enter from the overflow exhaust port b611. The extension direction of the overflow exhaust port b611 is set at an angle to the extension direction of the water vapor inlet b616. In this embodiment, the two are set perpendicularly, so that the liquid or gas from the second side of the overflow exhaust structure cannot enter the overflow exhaust structure from a direction parallel to the extension 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.

[0067] The overflow exhaust structure provided in this embodiment is shielded by setting a water-blocking end cover b614 in the extension direction of the water vapor inlet b616, so that the liquid or gas flows according to the prescribed 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 unobstructed state.

[0068] Preferably, in this embodiment, the first side of the overflow and exhaust structure along the axial direction is at least partially penetrated to form the water vapor inlet b616, and the second side of the overflow and exhaust structure along the axial direction is blocked to form the water retaining end cap b614. The overflow and exhaust port b611 is formed along the radial direction of the overflow and exhaust structure and near the water retaining end cap b614.

[0069] Specifically, the water retaining rib b613 is arranged at the upper edge of the water vapor inlet b616.

[0070] Preferably, the water retaining rib b613 is arranged on the conductive path between the water vapor inlet b616 and the overflow exhaust port b611, and is preferably arranged at a position corresponding to the overflow exhaust port b611. In this embodiment, the overflow exhaust port b611 includes at least an upper overflow exhaust port that opens upward. In this case, the water retaining rib b613 is arranged at the upper edge of the water vapor inlet b616 to block and guide the liquid or gas entering from the upper overflow exhaust port, so that the liquid or gas moves or drips along the side wall of the water retaining rib b613, avoiding direct entry into the water vapor inlet b616. As a result, the liquid or gas at a specific angle from the second side of the overflow exhaust structure is not only blocked by the water retaining end cap b614, but also blocked again by the water retaining rib b613 after a small portion of the liquid or gas enters the overflow exhaust structure, thereby reducing the occurrence of liquid or gas entering the overflow exhaust structure due to splashing.

[0071] Preferably, the water retaining rib b613 is arranged parallel to the water retaining end cover b614, and preferably, the setting direction of the water retaining rib b613 is perpendicular to the first direction. At this time, the cooperation between the water retaining rib b613 and the water retaining end cover b614 enables the guide channel inside the overflow exhaust structure to form a T-shaped structure. The liquid or gas entering from the second side can move or drip along the direction perpendicular to the first direction under the action of the water retaining rib b613, thereby increasing the difficulty of the liquid or gas from the second side of the overflow exhaust structure entering the overflow exhaust structure.

[0072] Specifically, the water vapor inlet b616 and the overflow exhaust port b611 are connected via a conductive hole b619. Preferably, the conductive hole b619 is located opposite the water retaining rib b613, enabling connection between the water vapor inlet b616 and the overflow exhaust port b611. Preferably, the conductive hole b619 is located at the lower edge of the water vapor inlet b616.

[0073] Specifically, the overflow exhaust port b611 is arranged perpendicular to the first direction and penetrates the overflow exhaust structure.

[0074] The overflow exhaust structure provided in this embodiment has an overflow exhaust port b611 that passes through the overflow exhaust structure perpendicular to the first direction, so that the guide channel inside the overflow exhaust structure forms a T-shaped structure, so that when liquid or gas enters the second side of the overflow exhaust structure, it can move or drip along a direction perpendicular to the first direction, thereby reducing the situation where liquid or gas from the second side of the overflow exhaust structure enters the overflow exhaust structure.

[0075] Specifically, the overflow exhaust ports b611 include at least two, and two adjacent overflow exhaust ports b611 are spaced apart by a partition boss b618.

[0076] Preferably, the overflow exhaust structure can be made by injection molding. The partition boss b618 arranged between two adjacent overflow exhaust ports b611 can, on the one hand, distinguish the overflow exhaust ports b611 at different angles, and on the other hand, support the water retaining end cover b614 by connecting the partition boss b618 with the water retaining end cover b614.

[0077] Specifically, the overflow exhaust structure includes at least an upper overflow exhaust port opening upwards and a lower overflow exhaust port opening downwards. By setting two exhaust ports, one opening upwards and the other opening downwards, it is convenient to divert the gas and liquid so that the gas with lower density can be discharged from the upper overflow exhaust port and the liquid with higher density can be discharged from the lower overflow exhaust port. Figure 3 As shown, S2 is the exhaust path and S3 is the overflow path.

[0078] Preferably, in this embodiment, the overflow exhaust structure is constructed as a hexagonal structure, and each edge of the hexagonal structure is provided with an overflow exhaust port b611, with a total of six overflow exhaust ports b611, and the six overflow exhaust ports b611 are arranged along a plane perpendicular to the first direction. By setting multiple overflow exhaust ports b611, the exhaust volume and drainage volume of the overflow exhaust structure can be conveniently increased.

[0079] Example 2

[0080] Combine Figure 2-Figure 3 As shown, this embodiment provides a water tank, comprising: a water tank body b9;

[0081] The overflow port b6 is formed by penetrating the side wall of one side of the water tank body b9; and the overflow exhaust structure as described in the above embodiment is connected to the overflow port b6.

[0082] Preferably, the water tank includes a water tank body b9 and an electrolysis device arranged inside the water tank; preferably, when the electrolysis device is arranged inside the water tank, the water tank can be an electrolysis water tank, and the electrolysis device is arranged inside the electrolysis water tank.

[0083] The water tank provided in this embodiment has an overflow port b6 formed on one side wall of the water tank. This allows excess water to be discharged 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 vapor inlet b616 of the overflow and exhaust structure, allowing liquid in the water tank to flow into the overflow and exhaust structure through the water vapor inlet b616 and be discharged through the overflow and exhaust port b611.

[0084] Specifically, the overflow port b6 is arranged near the top of the water tank, so as to ensure that the water tank has a larger volume and discharge water exceeding the set volume.

[0085] The overflow port b6 of the water tank is in communication with the water vapor inlet b616 of the overflow and exhaust structure. That is, the overflow port b6 of the water tank is located on the first side of the overflow and exhaust structure. Liquid or gas contained in the water tank is adapted to enter through the water vapor inlet b616 of the overflow and exhaust structure and, after passing through the through-channel within the overflow and exhaust structure, be discharged through the overflow and exhaust port b611 located on the second side of the overflow and exhaust structure. This allows the water in the water tank to be discharged along a prescribed path while also shielding liquid or gas at a specific angle from the second side of the overflow and exhaust structure, thereby reducing the influx of external water into the water tank.

[0086] Specifically, an overflow port flange b63 is arranged around the overflow port b6, and a screw-on portion b617 is arranged on the overflow exhaust structure at a position corresponding to the overflow port flange b63; an internal thread or an external thread is arranged on the overflow port flange b63, and an external thread or an internal thread is arranged correspondingly on the screw-on portion b617.

[0087] The overflow vent structure can be installed on the water tank by cooperating with the overflow flange b63 and the screw-on portion b617. Preferably, the overflow flange b63 is located on the outside of the water tank. Alternatively, the overflow flange b63 can be located on the inside of the water tank or on both sides of the first water tank sidewall b904 along the thickness direction. Correspondingly, the screw-on portion b617 is located on the first side of the overflow vent structure, preferably circumferentially outside the water vapor inlet b616, to facilitate direct connection between the water vapor inlet b616 and the overflow port b6.

[0088] Specifically, an anti-backflow rib b62 is provided at the lower edge of the overflow port b6, and the anti-backflow rib b62 is suitable for at least partially shielding the overflow port b6.

[0089] Specifically, the lowest point of the anti-backflow rib b62 in the up-down direction is higher than the lowest point of the conducting hole b619 inside the overflow exhaust structure.

[0090] Combine Figure 2 、 Figure 3 As shown, when the overflow flange b63 is positioned outside the water tank, the water vapor inlet b616 directly engages the overflow port b6, and the anti-backflow rib b62 is positioned above the lowest point of the water vapor inlet b616. Furthermore, the lowest point of the anti-backflow rib b62 in the vertical direction is higher than the lowest point of the conductive hole b619 within the overflow vent structure. This ensures that the lowest point of the water tank overflow port b6 is higher than the lowest point of the overflow vent structure connected thereto. Consequently, water overflowing from the water tank and entering the water vapor inlet b616 will be blocked by the anti-backflow rib b62, preventing backflow. Furthermore, external water entering the overflow vent b611 will also be blocked by the anti-backflow rib b62 as it flows into the water tank, thereby reducing the probability of external water entering the water tank.

[0091] The water tank provided in this embodiment is provided with an anti-backflow rib b62, and the lowest point of the anti-backflow rib b62 in the up and down direction is higher than the lowest point of the conductive hole b619 inside the overflow exhaust structure. Therefore, after the water overflowing from the water tank enters the water vapor inlet b616, it will be blocked by the anti-backflow rib b62 to prevent backflow; and after the external water enters from the overflow exhaust port b611, it will also be blocked by the anti-backflow rib b62 in the process of flowing into the water tank, thereby reducing the probability of external water entering the water tank.

[0092] Specifically, when the overflow vent structure is assembled with the water tank body b9, at least a portion of the screw-on portion b617 abuts against the anti-backflow rib b62, thereby improving the tightness of the assembly between the overflow vent structure and the water tank.

[0093] Specifically, when the overflow exhaust structure and the water tank body b9 are assembled, the anti-backflow ribs b62 and the water retaining ribs b613 are spaced apart in the horizontal direction and staggered in the up-down direction.

[0094] The water tank provided in this embodiment changes the water flow path into a broken line shape by staggering the anti-backflow ribs b62 and the water retaining ribs b613 in the up and down directions. On the one hand, the external water flow can be blocked multiple times when flowing into the water tank, while on the other hand, it does not affect the discharge of liquid inside the water tank.

[0095] Specifically, the backflow prevention rib b62 is arranged parallel to the water retaining rib b613. This facilitates manufacturing and, when the overflow exhaust structure is screwed onto the water tank body b9, the backflow prevention rib b62 and the water retaining rib b613 are arranged parallel to each other and spaced apart, so that they do not interfere with each other during rotation.

[0096] Example 3

[0097] Combine Figure 8 As shown, this embodiment provides a dishwasher, comprising:

[0098] Liner d5; and

[0099] A water tank as described in the above embodiment is installed outside the inner tank d5.

[0100] Preferably, the inner tank d5 wraps the interior of the dishwasher to form a cavity structure.

[0101] Preferably, the inner liner d5 includes an inner liner wall, and accordingly, the water tank body b9 includes a first water tank side wall b904. The inner liner wall is the side wall of the inner liner d5 that is attached to the water tank body b9. Correspondingly, the first water tank side wall b904 is the side wall of the water tank body b9 that is attached to the inner liner d5; the inner liner wall is attached to the first water tank side wall b904.

[0102] Specifically, the water tank is provided with an overflow port b6, and the inner tank d5 is provided with a through hole at a position corresponding to the overflow port b6; the water tank b0 and the inner tank d5 are connected via an overflow exhaust structure.

[0103] Preferably, the overflow port b6 is communicated with the through hole.

[0104] Preferably, the overflow port b6 of this embodiment is formed on the first water tank side wall b904; correspondingly, the through hole is formed on the inner tank wall. The water tank is located on the first side of the overflow and exhaust structure, and correspondingly, the inner tank d5 is located on the second side of the overflow and exhaust structure.

[0105] Specifically, an overflow seal b64 is provided between the water tank and the inner container d5, surrounding the overflow port b6. This placement of the overflow seal b64, surrounding the overflow port b6 and located between the water tank and the inner container d5, ensures a tight seal between the water tank and the inner container d5, preventing water from overflowing into the gap between the water tank and the inner container d5, preventing dripping and improving safety.

[0106] The dishwasher further comprises a spray arm d1 adapted to spray water, Figure 8 As shown, the water flow spraying direction S1 of the spray arm d1 is along a vertical direction or an inclined direction.

[0107] The dishwasher provided in this embodiment connects the water tank and the inner tank d5 through an overflow exhaust structure, so that the water tank 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 flows into the water vapor inlet b616 of the overflow exhaust structure and is discharged into the inner tank d5 from the overflow exhaust port b611; and the liquid at a specific angle sprayed from the inner tank d5 is blocked by the overflow exhaust structure, reducing the occurrence of water in the inner tank d5 flowing into the water tank.

[0108] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
