In the related art, as shown in fig. 1, in a dishwasher, air inlets X are respectively formed at both sides of an inner tub 100 of the dishwasher, and a drying air flow enters the inner tub 100 through the air inlets X at one side, dries tableware placed in the inner tub 100, and is discharged through the air inlets X at the other side. It can be seen that the airflow through the dishwasher is a single flow and the exhaust airflow is lost directly and cannot be reused. Furthermore, the drying air flow needs to be regenerated to maintain the drying effect, resulting in an increase in power consumption of the dishwasher.

To this end, the embodiment of the present application provides a novel dishwasher, and a drying mechanism in the dishwasher is improved, and a detailed description thereof will now be provided. Referring to fig. 2 and 3 (arrows in the drawings indicate the flow direction of the air flow), the dishwasher includes an inner container 100, a first fan 1, an inner flow pipe 2, and a control valve 3.

The inner container 100 is provided with an air inlet 101 and an air outlet 102, and the air inlet 101 and the air outlet 102 are respectively arranged on the opposite side walls of the inner container 100. It is understood that the air inlet 101 is located on one side wall of the inner container 100, and the air outlet 102 is located on the other side wall of the inner container 100.

The first fan 1 is used to discharge air inputted into the dishwasher toward the air inlet 101, forming an air flow for drying dishes in the inner tub 100.

The inner flow tube 2 is disposed outside the inner container 100 and is respectively communicated with the air inlet 101 and the air outlet 102.

The control valve 3 is used to control the air flow direction, so that the air discharged from the air outlet 102 flows back to the inner container 100 through the inner flow tube 2.

Compared with the prior art, the dishwasher provided by the embodiment of the application is provided with the internal flow pipe 2 and the control valve 3 in the dishwasher, and the two ends of the internal flow pipe 2 are respectively communicated with the air inlet 101 and the air outlet 102 on the liner 100, so that the drying air flowing through the liner 100 can flow in an internal circulation manner under the control of the control valve 3, the air flow is effectively prevented from being lost easily, and a constant temperature effect is achieved.

The dishwasher may be controlled by the control valve 3 according to the operation process. For example: in the drying process, as shown in fig. 3, the control valve 3 guides the airflow discharged from the air outlet 102 to the inner flow pipe 2, and the airflow flows back to the inner container 100 through the inner flow pipe 2, so that the airflow circulates in the dishwasher, thereby reducing airflow loss, achieving a constant temperature effect, and effectively reducing energy consumption of the dishwasher. Another example is: in the non-drying process, as shown in fig. 2, the control valve 3 closes the communication with the inner flow pipe 2, allowing the drying air to be directly discharged. On one hand, the odor in the liner 100 can be removed; on the other hand, prevent that some water liquid that spills from gas outlet 102 from getting into interior flow tube 2 to on flowing back to first fan 1 along interior flow tube 2, avoid causing the risk of wading to first fan 1 or heater block.

In an embodiment of the present application, referring to fig. 2 and 3, the dishwasher further includes an air inlet passage 4 and an air outlet passage 5 respectively communicated with the inner container 100, the air inlet passage 4 is connected with the air inlet 101, and the first fan 1 is disposed in the air inlet passage 4.
