As shown in FIG. 1 , a dishwasher according to the present invention includes a water storage tank 3 , and the water storage tank 3 stores filtered washing water for next washing. The filtered washing water is water after the washing water in the washing chamber 12 of the dishwasher is filtered by the filter unit of the dishwasher. The filtered washing water is stored in the water storage tank 3 for the next washing, which saves the water used for washing, saves energy and protects the environment, and improves the practicability of the dishwasher.

Embodiment one

As shown in Figure 1, the dishwasher described in this embodiment includes a water tank 10, and the water tank 10 is arranged at the bottom of the washing chamber 12 of the dishwasher for collecting the washing water in the washing chamber 12, filtering The unit is used to filter wash water in the water tank 10 . The water tank 10 communicates with the circulation pump 8. Preferably, the water tank 10 communicates with the circulation pump 8 through a heating unit. The heating unit is a heating pipe 9 for heating the washing water entering the circulation pump 8 from the water tank 10. The heating pipe 9 is Controllable, the user can choose to heat or not to heat. The water outlet of the circulation pump 8 communicates with the water storage tank 3 , and the circulation pump 8 introduces the filtered washing water into the water storage tank 3 .

Further, the dishwasher further includes a spray unit, the water outlet of the circulation pump 8 communicates with the spray unit and the water storage tank 3 , and the circulation pump 8 supplies the spray unit and the water storage tank 3 with filtered washing water.

Furthermore, the water outlet of the circulation pump 8 communicates with the spray unit and the water storage tank 3 through the water diversion valve 7 . The water diversion valve 7 controls the water outlet of the circulating pump 8 to communicate with the spray unit, or communicate with the water storage tank 3 , or communicate with the spray unit and the water storage tank 3 at the same time. The circulation pump 8 communicates with the spray unit and the water storage tank 3 through the water diversion valve 7, so that by controlling the water diversion valve 7, the circulation pump 8 can selectively supply the filtered washing water to the spray unit or the water storage tank 3, Or supply the spray unit and the water storage tank 3 at the same time.

Embodiment two

As shown in Figure 1, in the dishwasher described in this embodiment, the spray unit includes a bottom spray 5, a middle spray 4 and a top spray 2, preferably, the diverter valve 7 is connected with the bottom spray 5 respectively. , middle spray 4, top spray 2 and water storage tank 3 are connected. The water diversion valve 7 is provided with a position switch for controlling on-off with the bottom spray 5, the middle spray 4, the top spray 2 and the water storage tank 3 respectively.

Specifically, the bottom spray 5, the middle spray 4, the top spray 2, and the water storage tank 3 are respectively communicated with the water diversion valve 7 through pipelines. By controlling the on-off of each position switch of the water diversion valve 7, the circulation pump 8 can be controlled to connect or disconnect with the corresponding pipeline. That is, by controlling the on-off of each position switch of the water diversion valve 7, the circulation pump 8 can be controlled to supply water for the bottom spray 5, the middle spray 4, the top spray 2 and the water storage tank 3. Users can choose one connection, two or three connections, or they can be connected or closed at the same time.

Embodiment three

As shown in FIG. 1 , in the dishwasher described in this embodiment, the top spray 2 and the water storage tank 3 share a position switch. The water storage tank 3 is arranged on the side wall of the dishwasher, the water storage tank 3 is provided with an overflow port 1, the overflow port 1 communicates with the washing chamber 12 of the dishwasher, and the height of the overflow port 1 is lower than that of the top spray 2 . The water diversion valve 7 communicates with the water storage tank 3 through the valve 6, and the valve 6 controls the water storage tank 3 to enter and exit the washing water.

When the position switch shared by the top spray 2 and the water storage tank 3 is turned on, the circulation pump 8 can supply the filtered washing water to the top spray 2 and the water storage tank 3 at the same time. The position of the spray 2 is higher, and the pipeline water resistance of the top spray 2 is greater than the pipeline resistance to the water storage tank 3 . As the circulation pump 8 continuously supplies the filtered washing water, the filtered washing water will gradually be injected into the water storage tank 3, and when the filtered washing water is filled in the water storage tank 3, the water diversion valve 7 and the water storage tank will be closed. The valve 6 between 3 and the pipeline between the water storage tank 3 and the water diversion valve 7 are disconnected. At this time, the circulating pump 8 can only supply the filtered washing water to the top spray 2.

When the dishwasher is washing next time, the valve 6 is opened, and the filtered washing water stored in the water storage tank 3 flows into the water tank 10 of the dishwasher through the water diversion valve 7, the circulation pump 8, and the heating pipe 9 in sequence, for use in the dishwasher. washing. In this way, the collection and utilization of filtered washing water can be realized without adding water pumps and without increasing the number of position switches of the water diversion valve 7 .

Embodiment four

As shown in Figure 1, in the dishwasher described in this embodiment, the external water source enters the water tank 10 through the connected water inlet valve 15, respirator 14, and water softener 13 in sequence, and the water inlet valve 15 controls the on-off of the external water source. The respirator 14 can prevent the water in the sink 10 from flowing back, and the water softener 13 can soften the clear water entering the dishwasher.

Further, the dishwasher also includes a drain pump 11, which communicates with the sink 10 and is used for draining the water in the sink 10 out of the dishwasher. The drain pump 11 can discharge excess washing water in the sink 10 for washing dishes. outside the machine.
