[0035] The first water inlet channel 10 has a first part and a second part distributed vertically. The first part extends in the vertical direction, and the lower end of the second part is connected to the first part. The second water inlet channel 20 includes a third part and a fourth part. The third part is arranged side by side with the first part in the left - right direction, and the fourth part is connected to the third part and arranged side by side with the second part. It can be understood that the third part of the second water inlet channel 20 is arranged side by side with the first part of the first water inlet channel 10 in the left - right direction to enhance the overall pressure - bearing capacity of the water tank 100. Moreover, the fourth part of the second water inlet channel 20 is also arranged side by side with the second part of the first water inlet channel 10 in the left - right direction to further enhance the overall pressure - bearing capacity of the water tank 100, thereby greatly improving the explosion - proof performance of the water tank 100.

[0036] In addition, in some specific examples, the second part of the first water inlet channel 10 and the fourth part of the second water inlet channel 20 are inclined away from the water storage cavity 30, which can make way for the water storage cavity 30 in the spatial layout of the water tank 100 to increase the water storage capacity of the water storage cavity 30, thereby improving the washing performance of the dishwasher.

[0037] Embodiment 3

[0038] The first water inlet channel 10 includes a first flow channel 11 and a second flow channel 12. The first flow channel 11 is connected to the second flow channel 12. The first flow channel 11, the second flow channel 12 and the second water inlet channel 20 are arranged side by side in the left - right direction to improve the structural strength of the water tank 100, thereby improving the explosion - proof performance of the water tank 100.

[0039] Specifically, when the dishwasher is filled with water, the water flow can flow through the first flow channel 11 and the second flow channel 12 in sequence and then enter the water softener for water softening treatment. Among them, the first flow channel 11 and the second flow channel 12 can be arranged side by side in the left - right direction to improve the structural strength of the first water inlet channel 10 and prevent the water tank 100 from being damaged due to excessive inlet water pressure. Further, the first flow channel 11, the second flow channel 12 and the second water inlet channel 20 are arranged side by side in the left - right direction. In this way, the first water inlet channel 10 and the second water inlet channel 20 support each other structurally and evenly distribute the loads received, thereby improving the structural strength of the water tank 100.

[0040] Refer to Figure 1 and Figure 2, in some embodiments of the present utility model, the water tank 100 is further provided with a drainage channel 40. The drainage channel 40 and the second water inlet channel 20 are respectively arranged on the left and right sides of the first water inlet channel 10 and are used for draining water from the dishwasher. Specifically, after the dishwasher finishes washing, the wastewater generated by washing can be discharged through the drainage channel 40. Among them, the first water inlet channel 10, the second water inlet channel 20, and the drainage channel 40 are densely distributed in the water tank 100, which can improve the structural strength of the water tank 100, thereby realizing the explosion-proof of the water tank 100. More specifically, when high-pressure water flow is introduced into the first water inlet channel 10, the drainage channel 40 and the second water inlet channel 20 provide support on the left and right sides of the first water inlet channel 10 to improve the pressure resistance of the first water inlet channel 10 and prevent the water tank 100 from being damaged.

[0041] In addition, in some specific examples of the present utility model, the drainage channel 40, the first part of the first water inlet channel 10, and the third part of the second water inlet channel 20 are arranged side by side in the left-right direction to improve the structural strength of the water tank 100.

[0042] Refer to Figures 1 to 3 , in some embodiments of the present utility model, the water tank 100 includes a bottom plate 50 and a cover plate 60.

[0043] Among them, the bottom plate 50 is provided with a plurality of ribs 51. The plurality of ribs 51 are arranged side by side and at intervals in the left-right direction. A flow channel is constructed between every two adjacent ribs 51, and the plurality of ribs 51 construct the first water inlet channel 10 and the second water inlet channel 20. The cover plate 60 is stacked with the bottom plate 50 and covers the side of the plurality of ribs 51 facing away from the bottom plate 50. Such a setting can improve the structural strength of the water tank 100.

[0044] Specifically, the first water inlet channel 10 and the second water inlet channel 20 can be constructed by a plurality of ribs 51, which is simple in processing and manufacturing, low in cost, and the ribs 51 can strengthen the overall structural strength of the water tank 100 and improve the explosion-proof performance of the water tank 100. In addition, the plurality of ribs 51 are arranged side by side in the left-right direction. Structurally, the plurality of ribs 51 support each other and disperse the pressure received by the water tank 100, thereby greatly improving the explosion-proof performance of the water tank 100. In addition, the plurality of ribs 51 can increase the contact area with the cover plate 60, thereby improving the connection strength of the cover plate 60.

[0045] In addition, in combination with the foregoing, the second water inlet channel 20 is arranged at the edge of the water storage cavity 30. It can be understood that the ribs 51 are arranged at the edge of the water storage cavity 30 to strengthen the edge part of the water storage cavity 30 and prevent the edge of the water storage cavity 30 from being damaged and leaking water, which affects the user experience.

[0046] Refer to Figures 1 to 3, in some embodiments of the present utility model, a plurality of ribs 51 are integrally formed with the bottom plate 50, and the cover plate 60 is bonded to the plurality of ribs 51; in this way, the structural strength of the water tank 100 can be further improved, and the assembly and molding of the water tank 100 are facilitated.

[0047] Referring to Figure 1 and Figure 2 , in some embodiments of the present utility model, the plurality of ribs 51 include a first rib 511 and a second rib 512. The first rib 511 is connected to the bottom of the water tank 100, and the second rib 512 surrounds the first rib 511 to define a first water inlet flow channel 10 between the first rib 511 and the second rib 512; in this way, the structural strength of the water tank 100 can be improved, thereby enhancing the explosion-proof performance of the water tank 100.

[0048] Specifically, the first rib 511 has two side surfaces in the left-right direction. The inner side surface of the second rib 512 corresponds to the first rib 511 and includes a first side surface and a second side surface. A first flow channel 11 is defined between the first side surface of the second rib 512 and the left side surface of the first rib 511, and a second flow channel 12 is defined between the second side surface of the second rib 512 and the right side surface of the first rib 511. Moreover, there is a gap between the free ends of the second rib 512 and the first rib 511 so that the first flow channel 11 and the second flow channel 12 are communicated. In this way, a first water inlet flow channel 10 in a U-shaped structure can be formed. The structure of the first water inlet flow channel 10 is concentrated, and the strength of the part of the water tank 100 corresponding to the first water inlet flow channel 10 can be enhanced.

[0049] Referring to Figure 1 and Figure 2 , in some embodiments of the present utility model, the bottom plate 50 is further provided with a plurality of reinforcing ribs 52. The plurality of reinforcing ribs 52 include a third rib 521 and a fourth rib 522. The third rib 521 is connected to at least one of the plurality of ribs 51, and the fourth rib 522 is connected to the third rib 521 and has an included angle with the third rib 521; to further improve the structural strength of the water tank 100, thereby enhancing the explosion-proof performance of the water tank 100.

[0050] Specifically, as described above, the cover plate 60 of the water tank 100 is formed by bonding with a plurality of rib strips 51. Therefore, a plurality of reinforcing ribs 52 can be provided on the bottom plate 50. The plurality of reinforcing ribs 52 are used to further increase the structural strength of the water tank 100, and the plurality of reinforcing ribs 52 can increase the assembly area of the cover plate 60, thereby improving the assembly strength of the cover plate 60. Among them, the plurality of reinforcing ribs 52 include a third rib strip 521 and a fourth rib strip 522. The third rib strip 521 can be connected to at least one of the aforementioned plurality of rib strips 51 to provide structural support for the flow channel and improve the pressure resistance of the flow channel. The fourth rib strip 522 can be connected to the third rib strip 521 and has an included angle, so that the third rib strip 521 and the fourth rib strip 522 form a quasi-arch or quasi-triangular structure to improve the structural strength of the water tank 100.

[0051] Furthermore, there are a plurality of third rib strips 521 and a plurality of fourth rib strips 522. The plurality of third rib strips 521 and the plurality of fourth rib strips 522 are cross-distributed on the bottom plate 50. The third rib strip 521 is inclined in the direction of approaching the second water inlet flow channel 20 in the top-down direction, and the fourth rib strip 522 extends in the vertical direction to further improve the structural strength of the water tank 100 and increase the connection area with the cover plate 60.

[0052] Referring to Figure 1 , in some embodiments of the present invention, the water tank 100 is further provided with a first air flow channel and an air vent 53. The first air flow channel is arranged at the edge of the water storage cavity 30 and on the side of the water storage cavity 30 close to the second water inlet flow channel 20. The air vent 53 is arranged at the upper part of the water tank 100. The first air flow channel is respectively communicated with the air vent 53 and the drain flow channel 40. In this way, the flow channels in the water tank 100 can be further densified, thereby improving the explosion-proof performance of the water tank 100.

[0053] Specifically, in the dishwasher, the first air flow channel is respectively communicated with the air vent 53 and the drain flow channel 40. When a siphon phenomenon occurs in the drain flow channel 40, the gas in the external environment can enter the drain flow channel 40 through the air vent 53 and the first air flow channel to maintain the air pressure balance in the drain flow channel 40 and prevent the waste water in the drain flow channel 40 from flowing back into the inner cavity of the dishwasher, causing pollution to the inner cavity of the dishwasher. Among them, the first air flow channel is arranged at the edge of the water storage cavity 30 and on the side of the water storage cavity 30 close to the second water inlet flow channel 20, so that the second water inlet flow channel 20 and the first air flow channel are densified on one side of the water storage cavity 30 to improve the structural strength of the water tank 100, thereby improving the explosion-proof performance of the water tank 100. Of course, there can be a plurality of air vents 53 to further improve the air pressure stability of the dishwasher.

[0054] In addition, the first through-air flow channel extends in the vertical direction, and the upper part of the first through-air flow channel and the upper part of the second water inlet flow channel 20 are arranged side by side in the left-right direction to improve the structural strength of the water tank 100; the lower part of the first through-air flow channel is arranged side by side with the first flow channel 11 and the second flow channel 12 of the first water inlet flow channel 10 and the lower part of the second water inlet flow channel 20 to improve the structural strength of the water tank 100.

[0055] Referring to Figure 1 and Figure 2 , in some embodiments of the present utility model, the water tank 100 is further provided with a second through-air flow channel, and the second through-air flow channel is respectively connected to the top of the water storage cavity 30 and the ventilation port 53; in this way, the air pressure balance of the water storage cavity 30 and the inner cavity of the dishwasher is maintained. Specifically, in the dishwasher, when the air pressure in the water storage cavity 30 changes, the second through-air flow channel can discharge the gas in the water storage cavity 30 to achieve pressure relief and prevent the water tank 100 from bursting; or, the second through-air flow channel can supplement gas to the water storage cavity 30 to maintain the air pressure balance and avoid the occurrence of backflow phenomenon.

[0056] In addition, the water tank 100 is further provided with a third through-air flow channel and a ventilation hole 54. The third through-air flow channel and the second water inlet flow channel 20 are respectively arranged on the left and right sides of the first through-air flow channel, and at least a part of the third through-air flow channel, the first through-air flow channel and the second water inlet flow channel 20 are arranged side by side in the left-right direction to further improve the structural strength of the water tank 100, thereby improving the explosion-proof performance of the water tank 100; the third through-air flow channel is respectively communicated with the first through-air flow channel and the ventilation hole 54, which can further improve the ventilation efficiency between the inner and outer spaces of the dishwasher, thereby greatly improving the air pressure stability of the dishwasher.

[0057] In some embodiments of the present utility model, the thickness dimension of the rib 51 is not less than 1.5 mm and not more than 3 mm; in this way, the structural strength and manufacturing cost of the water inlet flow channel can be taken into account; it can be understood that if the thickness dimension of the rib 51 is less than 1.5 mm, the thickness of the rib 51 is too thin and its pressure-bearing capacity is low; if the thickness dimension of the rib 51 is greater than 3 mm, the thickness of the rib 51 is too thick, the processing and manufacturing cost is high, and the weight of the water tank 100 is increased. Among them, the thickness dimension of the rib 51 can be 1.5 mm, 1.8 mm, 2 mm, 2.5 mm, 3 mm, etc.

[0058] In some embodiments of the present utility model, the height dimension of the rib 51 is not less than 14 mm and not greater than 36 mm; in this way, the structural strength and manufacturing cost of the water inlet channel can be taken into account; it can be understood that if the height dimension of the rib 51 is less than 14 mm, the water inlet flow rate of the water inlet channel will be affected, resulting in a longer water inlet time; if the height dimension of the rib 51 is greater than 36 mm, the pressure-bearing capacity of the rib 51 is low, it is easily damaged by pressure, and the manufacturing cost is high. Among them, the height dimension of the rib 51 can be 14 mm, 16 mm, 20 mm, 25 mm, 30 mm, 36 mm, etc.

[0059] In some embodiments of the present utility model, the inner diameter dimension of the second flow channel 12 is not less than the inner diameter dimension of the first flow channel 11; specifically, the flow rate detection member 70 can be arranged in the first flow channel 11, and the one-way valve 80 can be arranged in the second flow channel 12; in the flow channel, the dimension required for installing the one-way valve 80 is not less than the dimension required for installing the flow rate detection member 70. Therefore, the inner diameter dimension of the second flow channel 12 can be made not less than the inner diameter dimension of the first flow channel 11 to facilitate the assembly of the one-way valve 80 and the flow rate detection member 70.

[0060] Refer to Figure 1 and Figure 2 In some embodiments of the present utility model, the first water inlet channel 10 is provided with a one-way valve 80, and the one-way valve 80 can control the one-way conduction from the inlet of the first water inlet channel 10 to the outlet 21 of the first water inlet channel 10; in this way, it can prevent the occurrence of siphon phenomenon when the dishwasher is filling with water, resulting in the reverse flow of the water inside the dishwasher to the water source and causing pollution to the water source.

[0061] Refer to Figure 1 and Figure 2 In some embodiments of the present utility model, the first water inlet channel 10 is further provided with a flow rate detection member 70, and the flow rate detection member 70 is arranged upstream of the one-way valve 80; in this way, when the dishwasher is filling with water, the flow rate detection member 70 can detect the water flow rate in the first water inlet channel 10, which is convenient for the dishwasher to introduce a predetermined amount of water flow and ensure the cleaning effect of the dishwasher; in addition, the flow rate detection member 70 is arranged upstream of the one-way valve 80, which can avoid the influence of reverse water flow on the detection accuracy of the flow rate detection member 70.

[0062] Refer to Figure 1 and Figure 2 In some embodiments of the present utility model, the outlet 21 of the second water inlet channel 20 is arranged at the top of the water tank 100 and communicates with the water storage cavity 30, which can reduce the water inlet pressure of the second water inlet channel 20 and avoid damage to the second water inlet channel 20.

[0063] Specifically, when water enters the water storage cavity 30, the outlet 21 of the second water inlet flow channel 20 is arranged at the top of the water tank 100. Therefore, water can enter from the top of the water storage cavity 30, and the pressure of the high-pressure water flow can be relieved through the space at the top of the water storage cavity 30, avoiding damage to the second water inlet flow channel 20 caused by excessive pressure. On the contrary, if the outlet 21 of the second water inlet flow channel 20 is arranged at the bottom of the water tank 100, water will enter from the bottom of the water storage cavity 30, and the stored water in the water storage cavity 30 will exert pressure on the second water inlet flow channel 20, and the high-pressure water flow entering will also exert pressure on the second water inlet flow channel 20, resulting in damage to the second water inlet flow channel 20.

[0064] In some specific examples, an overflow port 31 is provided at the top of the water tank 100. The overflow port 31 communicates with the water storage cavity 30, facilitating overflow when the water storage volume in the water storage cavity 30 exceeds a predetermined value, and the overflow port 31 can communicate with the external atmosphere. In other words, the pipeline pressure of the second water inlet flow channel 20 can also be relieved by communicating with the external atmosphere through the overflow port 31.

[0065] Refer to Figures 1 to 3 According to the dishwasher of the embodiment of the present utility model, the dishwasher includes the water tank 100 in the above embodiment. By applying the aforementioned water tank 100, the structural strength of the dishwasher can be improved, thereby improving the working stability of the dishwasher.

[0066] Specifically, the water tank 100 is provided with a first water inlet flow channel 10, a second water inlet flow channel 20, a water storage cavity 30, and a drainage flow channel 40. When the dishwasher is working, water can enter the water softener through the first water inlet flow channel 10 of the water tank 100 for water softening treatment, and then enter the water storage cavity 30 through the second water inlet flow channel 20. The water storage cavity 30 can wash the inner cavity of the dishwasher through the washing water flow. Subsequently, the wastewater generated in the inner cavity of the dishwasher can be discharged outside the dishwasher through the drainage flow channel 40.
