When the water storage unit 12 is not available, in order to supply water to the washing unit 11, the port corresponding to the third water inlet 124 and the port corresponding to the third water outlet 125 only need to be directly communicated.

The washing process of the dishwasher of the present embodiment can be roughly divided into an initial washing stage, a rinsing or subsequent washing stage, and a pre-washing stage.

Wherein, the condition of the initial washing stage is as follows: the first shut-off valve 171 is closed, and the second shut-off valve 172 is opened, so that all of the stored water in the water storage unit 12 flows into the inner container 111 through the second connecting line 16, thereby emptying the water storage unit 12. The water originally stored in the water storage unit 12 is filled before the last washing is finished, and the stored water can perform sufficient heat exchange with the environment where the dishwasher is located due to sufficient standing time, so that the temperature of the stored water is higher than the temperature of the conventional inlet water, and compared with the conventional inlet water, the energy consumption required by heating water in the dishwasher 1 can be reduced, and the energy is saved.

The initial wash was as follows: the first cut-off valve 171 is opened and the second cut-off valve 172 is closed, and the washing water of the water source flows into the water storage unit 12 through the water supply line 14, the water inlet line 131 of the breather unit 13, and the resin container 184 of the water softener 13, so that the water storage unit 12 can be filled. At this stage, the inner container 111 is in a working state for washing dishes, and the temperature of the water stored in the water storage unit 12 is increased due to the non-heat insulation between the inner container 111 and the water storage unit 12, thereby achieving the effect of saving energy.

The rinsing or subsequent washing phases are as follows: the first cut-off valve 171 is closed and the second cut-off valve 172 is opened to empty the water storage unit 12, and since the temperature of the stored water in the water storage unit 12 is higher than that of the normal intake water, a part of energy can be saved.

The case of the pre-end stage of washing is as follows: the first shut-off valve 171 is opened and the second shut-off valve 172 is closed, so that the washing water of the water source flows into the water storage unit 12 through the water supply line 14, the water inlet line 131 of the breather unit 13, and the resin container 184 of the water softener 13, and the water storage unit 12 can be filled. When water is filled into the water storage unit 12 at this stage, the inner container 111 is in operation, and heat in the inner container 111 can be transferred to the water storage unit 12, so that the temperature of water in the water storage unit 12 is increased, and the effect of saving energy in the next washing is achieved.
