The dish washing powder groove 400 is arranged on the door body 310, so that dish washing powder can be conveniently added, and meanwhile, the dish washing powder groove 400 can be maintained conveniently.
In an embodiment of the present invention, the dishwasher further includes a bowl basket 500 disposed in the inner container 300, and the spray arm assembly is located at the bottom of the bowl basket 500; the bottom of the bowl basket 500 is provided with a second driving member 230 for driving the shielding member 210 to open the side punched hole 101 when the spray arm body 100 moves to the side punched hole 101 close to the dishwashing powder slot 400.
In this embodiment, the bowl basket 500 is used for accommodating tableware, and the spray arm assembly is located at the bottom of the bowl basket 500, so that the tableware on the bowl basket 500 can be washed from different directions and different positions through the movement of the spray arm assembly. The second driving member 230 is configured as a limiting member installed on the bowl basket 500, and the position of the limiting member is located at an upstream position on the movement track of the spray arm body 100 close to the dishwashing powder tank 400, so that when the side punching hole 101 is about to be opposite to the dishwashing powder tank 400, the shielding member 210 is driven to open the side punching hole 101, and thus the washing effect of the side punching hole 101 on the dishwashing powder tank 400 is ensured. When the spray arm body 100 continues to move to drive the side punched hole 101 to gradually move away from the dishwashing powder tank 400, the limiting member releases the acting force on the shielding member 210, so that the shielding member 210 returns to the position for shielding the side punched hole 101 under the action of the first driving member 220 to prevent water from being sprayed continuously.
Optionally, the shielding member 210 is provided with a protruding member 214, and the protruding member 214 and the retaining member are in abutting engagement, so as to open the side punching hole 101.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
