The whole height of the table washing machine is effectively reduced, and the volume is reduced.

The air chamber on the drain valve of the washing machine is communicated up and down, the air tap at the upper end of the air chamber is matched and connected with the water level sensor through the air pipe, and the lower end of the air chamber is hermetically connected with the air chamber cover. The air chamber is communicated up and down, and the manufacturing process is simple.

The utility model has the advantages that the port axis is taken over in the outer drainage of valve main part bottom at horizontal position, is 45 to 135 contained angles with the axis of valve main part, and the bottom parallel and level of port bottom and valve main part are taken over in the outer drainage. Compared with the existing drain valve for the washing machine, the height of the drain valve is obviously reduced, so that the overall height of the table washing machine is effectively reduced, and the volume is reduced. The overflow port on the bottom surface of the washing machine is directly connected with the overflow port end of the drain valve for the washing machine; the air chamber on level sensor and the washing machine drain valve is connected, has saved the connecting tube, has reduced the requirement to washing machine accommodation pipeline space, makes the clearance between the interior bucket and the outside bucket reduce, and more effectual messenger table type washing machine's whole height obtains reducing, and the volume reduces.
