[0037] The sealing connection part 5 is arranged between the cover body 4 and the spray arm pipe fitting 2 to form a closed water path, so as to realize the sealing flow channel design without external pipeline. The structural sealing replaces the traditional sealing ring, avoids the leakage hidden danger caused by the aging of the rubber part, and simplifies the assembly complexity of the water path system.
[0038] In the embodiment, a plurality of annular sealing welding ribs are arranged between the cover body 4 and the spray arm pipe fitting 2, the cover body 4 and the spray arm pipe fitting 2 are fixedly connected by the annular sealing welding ribs, and the annular sealing welding ribs form the sealing connection part 5.
[0039] The inner container body 1 is provided with a spray arm mounting seat 8 for mounting the first spray arm assembly 3, and the spray arm mounting seat 8 and the inner container body 1 are integrally formed and constitute an undetachable whole.
[0040] Alternatively, the spray arm mounting seat 8 and the inner container body 1 are connected in a split type, a sealing member is arranged between the spray arm mounting seat 8 and the inner container body 1, and the spray arm mounting seat 8 and the inner container body 1 are sealingly matched through the sealing member.

The split type design cooperates with the sealing member, and the convenience of maintenance and replacement is reserved. Both the two implementation manners can ensure the sealing reliability of the spray arm assembly during long-term work.
[0042] In the embodiment, the spray arm pipe fitting 2, the spray arm mounting seat 8 and the inner container body 1 are integrally formed by injection molding.
[0043] The spray arm mounting seat 8 and the first spray arm assembly 3 are provided with a positioning and connecting matching part 10, and the spray arm mounting seat 8 and the first spray arm assembly 3 are positioned and connected through the positioning and connecting matching part 10.

[0053] The inner container water guide 1.1 and the inner container body 1 are integrally formed and constitute an undetachable whole. Alternatively, the inner container water guide 1.1 and the inner container body 1 are connected in a split type.
[0054] Referring to Figures 7-10 A dishwasher includes the above-mentioned inner container structure and a water collecting cup 12 arranged at a lower position of the inner container body 1. The water collecting cup 12 is provided with a water inlet opening 13 communicating with the inner container body 1. The water collecting cup 12 is provided with a drainage waterway assembly and / or a water inlet waterway assembly communicating with the water inlet opening 13. Liquid in the inner container body 1 is discharged out of the dishwasher through the water inlet opening 13 and the drainage waterway assembly. The water outlet end of the water inlet waterway assembly communicates with the spray arm pipe fitting 2, so that the inner container body 1, the water inlet assembly and the spray arm pipe fitting 2 constitute a circulating washing waterway.

[0057] In the embodiment, the water collecting cup 12 is provided with a water drainage pump mounting cavity 21 corresponding to the water inlet of the water drainage pump 14 and the water outlet of the water drainage pump 15, and the water inlet of the water drainage pump 14 and the water outlet of the water drainage pump 15 are respectively communicated with the water drainage pump mounting cavity 21.
[0058] The water inlet assembly includes a water inlet of the washing pump 16 and a water outlet of the washing pump 17 arranged on the water collecting cup 12.
[0059] In the embodiment, the water collecting cup 12 is provided with a washing pump mounting cavity 22 corresponding to the water inlet of the washing pump 16 and the water outlet of the washing pump 17, and the water inlet of the washing pump 16 and the water outlet of the washing pump 17 are respectively communicated with the washing pump mounting cavity 22.
[0060] In the embodiment, the water collecting cup 12 is internally provided with a water outlet communicated with the water drainage assembly and the water inlet assembly.
[0061] The water collecting cup 12 is provided with a heating tube 18 for heating liquid, and a heat shield 19 is arranged between the heating tube 18 and the water collecting cup 12.
[0062] In the embodiment, the water collecting cup 12 is provided with a stepped position 23 for mounting the heat shield 19, and the water collecting cup 12 is provided with a turbidity sensor 20 for detecting liquid.
[0063] The turbidity sensor 20 mainly works by optical principle. It usually contains a light source and a light receiver (or photosensitive element). The light source emits light of a specific wavelength, and when these light rays pass through the water sample, they are scattered by the particles in the water. The light receiver receives these scattered light, and calculates the turbidity in the water by measuring the intensity of the scattered light. The intensity of the scattered light is proportional to the concentration of suspended particles in the water, so it can be used to evaluate the cleanliness or transparency of the water.
[0064] Turbidity sensors are widely used in various occasions, such as household appliances (washing machines, dishwashers, etc.) for measuring water pollution to determine the optimal washing time; in industrial field control, environmental sewage collection, etc. for turbidity detection control; in addition, they are also commonly used in water treatment plants, environmental monitoring sites, sewage treatment plants, etc. to monitor water quality changes.
[0065] The working principle of the turbidity sensor 20 is based on the law of light scattering, and also involves the measurement of transmitted light. Some advanced turbidity sensors use the ratio of scattered light to transmitted light to replace the simple scattered light measurement of turbidity, which can improve the accuracy, reliability and anti-pollution of the sensor.
[0066] In the embodiment, the bottom of the water collecting cup 12 is provided with a buckle position for mounting and fixing the turbidity sensor 20. The turbidity sensor 20 is fixedly arranged on the bracket, the bracket is buckled with the buckle position, and the probe of the turbidity sensor 20 extends into the water collecting cup 12.

One end of the spray arm waterway 24 is communicated with the water outlet waterway 17 of the washing pump, and the second end of the spray arm pipe fitting 2 is communicated with the spray arm waterway 24. The second end of the spray arm pipe fitting 2 and the spray arm waterway 24 are connected in transition sealing fit through the corresponding dishwashing machine fitting. Here, those skilled in the art can adjust according to the needs, which will not be discussed in detail here.
[0068] In the embodiment, the water collecting cup 12 is integrally formed with the drain waterway assembly, the water inlet waterway assembly and the spray arm waterway 24 through an injection molding process.
[0069] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
