Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a drainage switching device for washing machines used in general households.

Conventional structure and its problems Conventionally, in the drainage switching structure of a washing machine, the first
As shown in the figure, a switch box 1 is provided on the upper surface of the washing tub, a lock lever 3 is rotatably attached to the lid 2 of the switch box 1, and a lock string is attached to a hook part 6 provided at one end of the switch box 1. 7 are connected. Further, a knob 5 is inserted into the shaft portion of the lever 3 projecting from the upper surface of the lid 2 to rotate the lever 3. The other end of the string 7 is connected to a frame 9 provided on the lower surface of a tank 8 forming a washing tub and a dehydrating tub. By rotating the knob 5, the drain string 7 is pulled upward, and the drain port of the drain frame 9 provided with the valve body is opened. By returning the knob 5 to its original position, the drain port is closed. With this configuration, it was possible to store and drain water from the washing tub. However, since such a drainage switching device is provided at the rear of the upper surface of the washing tub, and the potting lever 3 is provided on the inclined surface of the lid 2, there is a problem that the washing tub input port becomes small. Recently, the width of the switch box has been made smaller and the input opening of the washing tub has been made larger to make it easier to put the laundry in. However, with the conventional configuration, the rotation length of the kettle lever 3 is long to some extent. Otherwise, the width of the switch box 1 could not be made smaller because the winding length of the string 7 would be short and the drainage time would be long.

Purpose of the invention The present invention solves these conventional problems and provides a drainage switching structure for a washing machine that can reduce the width of the switch box and enlarge the washing tub input opening. be.

Structure of the invention The drainage switching device of the present invention has a cross section that can move freely in a linear direction and a rotatable cross arm that can be rotated, and by moving the cross section in a linear direction, the drain opening of the cross frame equipped with a valve body can be opened and closed. It is something to do.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 2, reference numeral 11 designates a panel with a locking block 12 disposed on its lower surface, and a locking knob 13 is inserted from the upper surface of the panel 11 through a hole 14 into a mounting hole 15 of the locking block 12, making it freely movable left and right. Further, an inverted U-shaped hook portion 16 is formed at one end of the locking rod 12. Further, a guide frame 17 is formed below the hook portion 16 toward the upper surface of the tank, and this guide frame 17
A recess 18 is formed approximately in the center of both side walls.
19 is the Kotoku arm, with boss 2 between the two boards.
0, 21 are provided, a Kotuku string 22 is attached to the boss 19, and the other end of the Kotuku string 22 is connected to a Kotuku frame 23. Further, bosses 24 are provided at the corners of the outer surfaces of the two plates, and the bosses 24 are mounted in the recesses 18 of the guide frame 17, and the cock arms 19 are inserted therein. From above, attach the hook portion 1 of the locking rod 12 to the boss 19 of the locking arm 19.
The panel 11 is attached so that the panel 6 fits into the panel.

To explain the operation in the above configuration, the state shown in FIG. 3 is the state shown in FIG. 3 when the drain port of the pot frame 23 is closed and the pot knob 13 is slid as shown in FIG. 4, the pot arm 19 rotates around the boss 24. In order to move, the boss 20 to which the Kotuku string 22 is attached moves upward. For this reason, Kotuku string 2
2 is pulled upward, the drain port of the pot frame 23 is opened, and the water in the washing tub is drained.

Effects of the invention As is clear from the above explanation, according to the invention, the drainage switching structure can be made more compact by changing the conventional rotation method to the sliding method for hoisting the switch box, thereby reducing the width of the switch box. As a result, the loading opening of the washing tub can be made larger, making it easier to put in and take out laundry. Furthermore, since the locking cord and the locking arm are in a mere engagement relationship, they can be separated, and the panel can be removed without removing the locking cord, making disassembly and assembly easy.
