[0027] As shown in Figures 1 to 7 The dish washing machine of the preferred embodiment includes an inner container 1 and a water cup 2, the water cup 2 is arranged at the bottom of the inner container 1, the water cup 2 is at least partially concave to form a backwater area 21, the backwater area 21 is in communication with the inner container 1, and the backwater area 21 of the water cup 2 is provided with a heating disc.

[0028] The above is the prior art, which will not be described here.

[0029] In this embodiment, the heating disc in the backwater area only needs to heat the water temperature to 75 DEG C, which is the normal working water temperature of the dish washing machine and will not affect the service life of the key components.

[0030] As shown in Figure 1 , As shown in 3 ~7, the water tank 3 is arranged at the bottom of the water cup 2, the inlet of the water tank 3 and the backwater area 21 are connected or disconnected through a water distribution valve 5, the water tank 3 is provided with a heating element 31, and the heating element 31 can adopt the existing structure. Downstream of the water tank 3 along the water flow direction, a steam box 4 is arranged, the water tank 3 and the steam box 4 are connected through a pipe body 41, a plurality of spray holes 42 are arranged on the steam box 4, and a plurality of spray nozzles 22 corresponding to the spray holes 42 are arranged on the top of the water cup 2, so that the outlet of the water tank 3 is connected with the spray nozzles 22, so that the steam can be sprayed at multiple points, and the spraying range is large. The steam box 4 can adopt a structure that generates heat to prevent steam condensation.

[0031] The high-temperature steam generated by heating in the water tank 3 quickly heats and softens the dirt on the tableware, making it easier to clean and improving the cleaning effect; the high-temperature steam can also sterilize and decontaminate the clean tableware.

[0032] In addition, the water path of the water tank 3 is communicated or disconnected with the water path in the water return area 2 through the water distribution valve 5. The water in the water return area of the inner container 1 is cleaning water, which is heated to 75 DEG C. This is the normal working water temperature of the dishwasher and does not affect the service life of the key components.

[0033] A small amount of water flows into the water tank 3 through the control of the water distribution valve 5, only this part of water is heated, and the water in the water tank 3 is used for steam generation and is heated to 100 DEG C. In this way, the water that needs to be heated to 100 DEG C is much less than the water in the inner container 1, the heating time is short, and the energy consumption is low.

[0034] In addition, all the water in the water tank 3 is used for steam generation, and there is no excess water to be discharged. In this way, the drain pipe does not need to discharge high-temperature water (close to 100 DEG C), and the risk of melting is avoided.

[0035] The outer side of the water tank 3 is wrapped with a heat insulation member, which can effectively reduce the temperature rise of the surrounding components. The heat insulation member can use existing heat insulation materials.
