[0010] Furthermore, an upper notch recessed inwardly in the radial direction is provided on the overflow port flange, and the upper notch forms a gap between the overflow exhaust structure and the overflow port flange, which is suitable for allowing the overflow port to at least partially communicate with the outside world.

[0011] Furthermore, the lower notch is arranged at a lower position of the overflow port flange, and the upper notch is arranged at an upper position of the overflow port flange.

[0012] Furthermore, the difference in length between the upper notch and the lower notch along the direction of penetration of the overflow port is L, wherein L>0 cm.

[0013] Furthermore, an external thread is provided on the outer surface of the overflow flange at a position corresponding to the upper recess and / or the lower recess.

[0014] Furthermore, the overflow exhaust structure is provided with a water vapor inlet side wall, which is suitable for surrounding the outside of the overflow port flange in the installed state, and the water vapor inlet side wall is provided with a side wall internal thread at a position corresponding to the external thread.

[0015] Furthermore, a water retaining end cover is provided on the overflow exhaust structure, and the water retaining end cover blocks one side of the side wall along the axial direction from which the water vapor enters.

[0016] Furthermore, a water retaining cover is provided on the overflow exhaust structure. The water retaining cover is arranged around the outside of the water vapor entry side wall and forms an exhaust cavity between the water vapor entry side wall and the water vapor entry side wall.

[0017] Furthermore, at least one exhaust and drainage gap is provided on the water retaining cover, and the exhaust and drainage gap is suitable for connecting the exhaust cavity with the outside.

[0018] Furthermore, a flange groove is provided in at least a partial area on the overflow flange, and a backflow prevention edge is provided in the middle position between the flange groove and the upper recess in the axial direction, and the height of the backflow prevention edge in the radial direction is higher than the height of the corresponding position of the flange groove.

[0019] The dishwasher provided by the present invention comprises:

[0020] liner;

[0021] a spray arm, disposed inside the inner container and adapted to spray water; and

[0022] A water tank assembly as described above is installed on the outside of at least one of the side walls of the inner tank.

[0023] Furthermore, a through hole is provided on the side wall of the inner tank at a position corresponding to the overflow port; the water tank assembly and the inner tank are connected via an overflow exhaust structure.

[0024] Furthermore, an overflow port sealing ring is provided between the water tank body and the inner tank, and the overflow port sealing ring is provided around the overflow port.

[0025] The technical solution of the present invention has the following advantages:

[0026] 1. In the water tank assembly provided by the present invention, the lower recess forms a gap between the overflow vent structure and the overflow port flange, so that the water flow inside the water tank body can be discharged from the lower recess through the overflow port on the one hand, and on the other hand, because the overflow vent structure at least partially covers the overflow port, liquid or gas from the outside of the water tank body is prevented from directly entering the overflow port in an unobstructed state.

[0027] 2. The water tank assembly provided by the present invention provides an upper recess on the overflow flange so that the overflow is at least partially connected to the outside world, facilitating the discharge of gas from the upper recess. The different densities of gas and liquid are utilized to separate the overflow path and the exhaust path, facilitating the diversion of gas and liquid, and further facilitating the differentiated treatment of gas and liquid.

[0028] 3. The water tank assembly provided by the present invention sets the lower recess and the upper recess at different positions of the overflow flange, so that the gas and liquid in the water tank can be discharged according to the prescribed path. The upper recess is set at the upper position of the overflow flange, which is convenient for utilizing the lower density of hydrogen to achieve gas buoyancy and discharge from the upper recess. The lower recess is set at the lower position of the overflow flange, which is convenient for utilizing the higher density of water to discharge water from the lower recess located at the bottom, thereby realizing the separation of the overflow path and the exhaust path.

[0029] 4. The water tank assembly provided by the present invention makes the length of the upper recess along the direction of penetration of the overflow port longer than the length of the lower recess along the direction of penetration of the overflow port, so that when the liquid from the outside of the water tank body slides downward and flows through the overflow port flange, when the water flows over the upper recess and drips downward, due to the length difference between the upper recess and the lower recess, the water flow in the upper recess will not drip directly onto the lower recess when dripping, but will drip downward into the overflow exhaust structure, thereby reducing water splashing and thus reducing the occurrence of liquid entering the overflow port.

[0030] 5. The water tank assembly provided by the present invention blocks one side of the water vapor inlet side wall along the axial direction through the water retaining end cover, 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] 6. The water tank assembly provided by the present invention, the lower recess and the upper recess form a gap between the overflow exhaust structure and the overflow port flange, thereby making the overflow port at least partially connected to the exhaust cavity, and by providing at least one exhaust and drainage notch on the water retaining cover, the exhaust cavity is connected to the outside, thereby facilitating the discharge of liquid or gas in the overflow port along a prescribed path.

[0032] 7. The water tank assembly provided by the present invention is further provided with an anti-backflow rib at the middle position along the axial direction between the flange groove and the upper recess. The height of the anti-backflow rib in the radial direction is higher than the height of the corresponding position of the flange groove, so that the liquid sliding down the side wall of the water tank body can slide along the circumference of the overflow flange when the water flow rate is small, thereby reducing the occurrence of water flowing into the water tank from the overflow port.

[0033] 8. The dishwasher provided by the present invention 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 or gas at a specific angle sprayed from the inner tank is blocked by the overflow exhaust structure, thereby reducing the occurrence of water in the inner tank flowing into the water tank.

[0053] 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.

[0054] Example 1

[0055] Combine Figure 4-11 As shown, the water tank assembly provided in this embodiment includes:

[0056] Water tank body b9;

[0057] The overflow port b6 is formed by penetrating the side wall of one side of the water tank body b9; and

[0058] an overflow exhaust structure b61, mounted on the outside of the water tank body b9, adapted to at least partially cover the overflow port b6; and

[0059] The overflow port flange b63 is arranged around the circumference of the overflow port b6 and is suitable for supporting the overflow exhaust structure b61;

[0060] The overflow port flange b63 is further provided with a lower recess b632 recessed inwardly in the radial direction. The lower recess b632 forms a gap between the overflow exhaust structure b61 and the overflow port flange b63, which is suitable for allowing the overflow port b6 to at least partially communicate with the outside world.

[0061] Preferably, the water tank b0 includes a water tank body b9 and an electrolysis device arranged inside the water tank b0; preferably, when the electrolysis device is arranged inside the water tank b0, the water tank b0 can be an electrolysis water tank, and the electrolysis device is arranged inside the electrolysis water tank.

[0062] Preferably, 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.

[0063] Before the water tank b0 is ready to start working, a preset flow of water needs to be introduced into the interior. When the flow meter or the switch valve fails, water will continue to 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 the water tank b0 overflows, the overflow alarm device reminds the user.

[0064] Preferably, the overflow port b6 is formed on the side wall of one side of the water tank, so that excess water can be discharged from the overflow port b6 when the water level inside the water tank is too high.

[0065] Preferably, the overflow exhaust structure b61 is suitable for at least partially covering the overflow port b6, and since the overflow exhaust structure b61 is installed on the outside of the water tank body b9, it prevents liquid or gas from the outside of the water tank body b9 from directly entering the overflow port b6 in an unobstructed state.

[0066] Preferably, the overflow port flange b63 is arranged around the circumference of the overflow port b6 and is suitable for supporting the overflow exhaust structure b61, so as to facilitate the installation of the overflow exhaust structure b61 on the overflow port flange b63.

[0067] Preferably, the overflow flange b63 is arranged around the overflow port b6 to form a cylindrical structure. The lower recess b632 is arranged at the edge of the overflow flange b63 on the side away from the water tank body b9, and the lower recess b632 is recessed inwardly along the radial direction of the overflow flange b63. ​​Therefore, when the overflow vent structure b61 and the overflow flange b63 are assembled, the presence of the lower recess b632 forms a gap between the overflow vent structure b61 and the overflow flange b63, thereby allowing the overflow port b6 to at least partially communicate with the outside world.

[0068] In the water tank assembly provided in this embodiment, the lower recess b632 forms a gap between the overflow exhaust structure b61 and the overflow port flange b63, so that the water flow inside the water tank body can be discharged from the lower recess b632 through the overflow port b6 on the one hand, and on the other hand, because the overflow exhaust structure b61 at least partially covers the overflow port b6, it prevents liquid or gas from the outside of the water tank body b9 from directly entering the overflow port b6 in an unobstructed state.

[0069] Specifically, the overflow port flange b63 is further provided with an upper notch b631 recessed inwardly in the radial direction. The upper notch b631 forms a gap between the overflow exhaust structure b61 and the overflow port flange b63, which is suitable for allowing the overflow port b6 to at least partially communicate with the outside world.

[0070] Preferably, the overflow flange b63 is arranged around the overflow port b6 to form a cylindrical structure. The upper recess b631 is arranged at the edge of the overflow flange b63 on the side away from the water tank body b9, and the upper recess b631 is recessed inwardly along the radial direction of the overflow flange b63. ​​Therefore, when the overflow vent structure b61 and the overflow flange b63 are assembled, the presence of the upper recess b631 forms a gap between the overflow vent structure b61 and the overflow flange b63, thereby allowing the overflow port b6 to at least partially communicate with the outside world.

[0071] Specifically, the lower notch b632 is provided at a lower position of the overflow port flange b63, and the upper notch b631 is provided at an upper position of the overflow port flange b63.

[0072] When the water tank b0 is working, the salt water is electrolyzed by the electrolysis device, and gas is generated during the electrolysis process. Most of the generated gas is hydrogen with low density, which will move upward. The hydrogen will pass through the overflow port b6 and be discharged from the upper recess b631.

[0073] The water tank assembly provided in this embodiment provides an upper recess b631 on the overflow flange b63, so that the overflow port b6 is at least partially connected to the outside world, facilitating the discharge of gas from the upper recess b631. By utilizing the different densities of gas and liquid, the overflow path and the exhaust path are separated, facilitating the diversion of gas and liquid, and further facilitating the differentiated treatment of gas and liquid.

[0074] The water tank assembly provided in this embodiment sets the lower recess b632 and the upper recess b631 at different positions of the overflow flange b63, so that the gas and liquid in the water tank can be discharged according to the prescribed path. The upper recess b631 is set at the upper position of the overflow flange b63, which facilitates the use of the lower density of hydrogen to achieve gas buoyancy and discharge from the upper recess b631. The lower recess b632 is set at the lower position of the overflow flange b63, which facilitates the use of the higher density of water to enable water to be discharged from the lower recess b632 located at the bottom, thereby achieving separation of the overflow path and the exhaust path.

[0075] Specifically, the difference in length between the upper notch b631 and the lower notch b632 along the direction of penetration of the overflow port b6 is L, wherein L>0 cm.

[0076] The water tank assembly provided in this embodiment makes the length of the upper recess b631 along the direction of penetration of the overflow port b6 longer than the length of the lower recess b632 along the direction of penetration of the overflow port b6, so that when the liquid from the outside of the water tank body b9 slides downward and flows through the overflow port flange b63, when the water flows over the upper recess b631 and drips downward, due to the length difference between the upper recess b631 and the lower recess b632, the water flow in the upper recess b631 will not drip directly onto the lower recess b632 when dripping, but will drip downward into the overflow exhaust structure b61, thereby reducing water splashing and thereby reducing the occurrence of liquid entering the overflow port b6.

[0077] Specifically, external threads are provided on the outer surface of the overflow flange b63 at positions corresponding to the upper recess b631 and / or the lower recess b632 .

[0078] Combine Figure 1-Figure 3 As shown, specifically, the overflow exhaust structure b61 is provided with a water vapor inlet side wall b67, which is suitable for surrounding the outside of the overflow port flange b63 in the installed state, and the water vapor inlet side wall b67 is provided with a side wall internal thread b672 at the position corresponding to the external thread.

[0079] The overflow exhaust structure b61 is installed on the overflow outlet flange b63 through the cooperation between the external thread and the internal thread correspondingly provided on the water vapor entry side wall b67 and the overflow outlet flange b63.

[0080] And since the position of the external thread on the overflow port flange b63 corresponds to the upper recess b631 and / or the lower recess b632, it can not only ensure the engagement of the overflow exhaust structure b61 with the overflow port flange b63, but also ensure that a gap is left between the two at the engagement position, thereby facilitating the exhaust and overflow of the upper recess b631 and the lower recess b632.

[0081] Specifically, a water retaining end cover b614 is further provided on the overflow exhaust structure b61, and the water retaining end cover b614 blocks the water vapor from entering one side of the side wall b67 along the axial direction.

[0082] The water vapor inlet side wall b67 is arranged around a circle, and its first side is open to form a water vapor inlet b616. The water vapor inlet b616 is arranged through the first side of the overflow exhaust structure; the water retaining end cover b614 is arranged on the second side of the overflow exhaust structure and is arranged along the extension direction of the water vapor inlet b616, which is suitable for blocking the extension direction of the water vapor inlet b616.

[0083] 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 at least partially penetrates the overflow exhaust structure, and the water vapor inlet b616 is suitable for passing liquid or gas. The second side of the overflow exhaust structure is provided with a water retaining end cover b614, and the water retaining end cover b614 is suitable for at least partially blocking or completely blocking the extension 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 unobstructed state.

[0084] The overflow port b6 is connected to the water vapor inlet b616 of the overflow exhaust structure, so that the liquid in the water tank can flow into the water vapor inlet b616 of the overflow exhaust structure and be discharged from the overflow exhaust port b611.

[0085] Preferably, in this embodiment, the liquid from the first side of the overflow exhaust structure overflows in a diffuse manner, and the liquid from the second side of the overflow exhaust structure overflows in a jet manner.

[0086] The overflow exhaust structure provided in this embodiment blocks one side of the water vapor entering side wall b67 along the axial direction through the water retaining end cover b614, so that the liquid or gas flows along the prescribed 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 vapor inlet b616 in an unobstructed state.

[0087] Preferably, in this embodiment, the overflow exhaust structure is constructed as a circular structure, and the first side along the axial direction of the overflow exhaust structure is at least partially penetrated 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 retaining end cover b614.

[0088] Specifically, a water retaining cover b65 is further provided on the overflow exhaust structure b61. The water retaining cover b65 is arranged around the outside of the water vapor entry side wall b67, and forms an exhaust cavity b66 between the water vapor entry side wall b67 and the water vapor entry side wall b67.

[0089] Specifically, at least one exhaust and drainage gap b651 is provided on the water retaining cover b65, and the exhaust and drainage gap b651 is suitable for connecting the exhaust cavity b66 with the outside.

[0090] Combine Figure 8 、 Figure 9 As shown, the exhaust path S2 and overflow path S3 inside the water tank assembly are shown in the figure. The exhaust and overflow both enter from the water vapor inlet b616, the exhaust path S2 is discharged through the upper recess b631, and the overflow path S3 is discharged through the lower recess b632.

[0091] The water tank assembly provided in this embodiment, the lower recess b632 and the upper recess b631 form a gap between the overflow exhaust structure b61 and the overflow port flange b63, thereby making the overflow port b6 at least partially connected to the exhaust cavity b66, and by providing at least one exhaust and drainage notch b651 on the water retaining cover b65, the exhaust cavity b66 is connected to the outside, thereby facilitating the discharge of liquid or gas in the overflow port b6 along a prescribed path.

[0092] Support ribs b652 are also connected between the water retaining cover b65 and the water vapor inlet side wall b67, which facilitates the structural reinforcement of the water retaining cover b65 and the division of the space in the exhaust cavity b66.

[0093] Preferably, the space of the exhaust cavity b66 defined between every two supporting ribs b652 corresponds to one of the exhaust drainage gaps b651, so that the liquid entering each exhaust drainage gap b651 only flows within the limited area, and the flow to other areas is reduced, thereby avoiding the liquid or gas from the outside of the water tank body b9 entering the exhaust cavity b66 from the exhaust drainage gap b651 and then flowing around in the exhaust cavity b66, so that the liquid in the exhaust cavity b66 is confined to one area as much as possible.

[0094] Specifically, a flange groove b633 is provided on at least part of the overflow flange b63, and a backflow prevention edge b634 is provided in the middle position between the flange groove b633 and the upper recess b631 in the axial direction. The height of the backflow prevention edge b634 in the radial direction is higher than the height of the corresponding position of the flange groove b633.

[0095] Preferably, the flange groove b633 is arranged at the upper position of the overflow flange b63, so that the liquid sliding down the side wall of the water tank body b9 can first enter the flange groove b633. The flange groove b633 can buffer and divert the liquid, so that the water flow can preferentially slide along the circumference of the overflow flange b63, reducing the possibility of entering the overflow port b6.

[0096] The water tank assembly provided in this embodiment is further provided with an anti-backflow rib b634 at the middle position along the axial direction between the flange groove b633 and the upper recess b631. The height of the anti-backflow rib b634 in the radial direction is higher than the height of the corresponding position of the flange groove b633, so that the liquid sliding down the side wall of the water tank body b9 can slide along the circumference of the overflow flange b63 when the water flow rate is small, thereby reducing the occurrence of water flowing into the water tank b0 from the overflow port b6.

[0097] Example 3

[0098] Combine Figure 12 As shown, this embodiment provides a dishwasher, comprising:

[0099] Liner d5;

[0100] a spray arm d1 , disposed inside the inner container d5 and adapted to spray water; and

[0101] The water tank b0 as described in the above embodiment is installed outside the inner tank d5.

[0102] Preferably, the inner tank d5 wraps the interior of the dishwasher to form a cavity structure.

[0103] Preferably, the inner liner d5 includes an inner liner wall d51, and accordingly, 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 that is attached to the water tank body b9, and 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 d51 is attached to the first water tank side wall b904.

[0104] 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.

[0105] 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 inner tank 5 has a large space and is equipped with an exhaust fan, the hydrogen is continuously discharged to the outside of the dishwasher, avoiding the potential explosion hazard caused by local hydrogen accumulation.

[0106] Preferably, the overflow port b6 is communicated with the through hole.

[0107] 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 d51. The water tank b0 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.

[0108] The dishwasher provided in this embodiment connects the water tank b0 and the inner tank d5 through an 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 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 or gas at a specific angle sprayed from the inner tank d5 is blocked by the overflow exhaust structure, thereby reducing the occurrence of water in the inner tank d5 flowing into the water tank b0.

[0109] Specifically, combined Figure 10 、 Figure 11 As shown, when the water flow from the spray arm d1 is sprayed onto the inner tank wall d51 in the spray direction S1 and slides down along the inner tank wall d51, if water flows into the overflow exhaust structure b61, under the condition of small water flow, the return path of the water tank assembly is as follows: Figure 10 As shown in the return direction S5 of the first spray arm, the return water will be blocked by the anti-backflow rib b634, and the water will slide along the circumference of the overflow flange b63 and finally flow back into the inner tank, preventing the water from entering the water tank b0 from the overflow port b6; in the case of a large water flow, the return path of the water tank assembly is as follows Figure 11 As shown in the backflow direction S6 of the second spray arm, a part of the water will overflow the anti-backflow rib b634 and flow into the upper recess b631. At this time, since the length of the upper recess b631 along the direction of penetration of the overflow port b6 is longer than the length of the lower recess b632, the water will flow along the rock wall of the upper recess b631 to the exhaust overflow exhaust structure b61, and finally flow back into the inner tank through the exhaust drainage gap b651, preventing the water from entering the water tank b0 from the overflow port b6.

[0110] Preferably, the spray arm d1 is at least partially disposed within the inner container d5. In this embodiment, the spray arm d1 is located in the middle of the inner container d5, and the water tank b0 is mounted on the side wall of the inner container d5, so that the overflow 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 spray direction S1 is shown in the figure.
