At least one or more protrusions 122 formed on the outer circumferential surface of the side wall portion 121 to be coupled to the formed lid fixing protrusion 60a to clamp the lid 120, so that the user can be easily removable to the outer case 60 Consists of a circular groove 124 formed on the upper surface It can control.

In the above description, the operation means 126 detects the amount of laundry by the laundry detection means 150 and inputs the laundry introduced into the combined washing / dehydration tank 11 to the input port IN3 of the microcomputer 139. At the output port OUT1 to dissolve the solid detergent 70 according to the amount of the laundry in the net container 44 in the detergent dissolving tank 42 to supply to the combined-use dehydration tank (11) (126) And a control signal is outputted to the flange. The actuating lever 126a of the actuating means 126 is connected to the flange portion 130b of the detergent feeding control lever 130 through a connection wire 149. Here, the operation lever 126a of the operation means 126 may be directly connected to the flange portion 130b of the detergent injection control lever 130.

The operation and effect of the solid detergent injector of the washing machine according to one embodiment of the present invention configured as described above will be described below.

First, the laundry to be washed is put in the washing / drying dehydration tank 11, and then the main switch of the washing machine is turned on. The laundry detection means 150 detects the weight of the laundry and converts the detected data into the microcomputer 139. Output to the input port (IN3). At this time, the microcomputer 139 calculates the amount of detergent to be administered to the combined laundry dehydration tank 11 according to the amount (weight) of the laundry, and outputs a control signal from the output port OUT1 to the operating means 126 for operating means. 126 is operated. Since the flange portion 130b of the detergent injection control lever 130 is connected to the operation lever 126a via the connection wire 140 by the operation of the operation means 126, the detergent injection control lever 130 is Detergent injection hole 62a formed in the bottom plate 62 of the outer case 60 by being rotated counterclockwise about the central axis 64 of the outer case 60 against the pulling force of the switching spring 132. And the detergent passage hole 130a formed in the detergent input control lever 130 are moved until they coincide with each other. When the detergent injection hole 62a and the detergent passage hole 130a coincide with each other, the solid detergent 70 placed on the bottom plate 62 in the state shown in FIG. 7 is indicated by a dotted line in FIG. Likewise, the solenoid 23 is dissolved by the washing water supplied through the water supply pipe 6 in the net container 44 in the detergent dissolution tank 42 and the air injected through the air injection hole 12a formed in the accelerator 12. By the opening of the washing water supply pipe 13 is supplied into the combined washing and dehydration tank (11).

In the above description, when one solid detergent 70 is dropped, the detergent input detection means 142 detects the data and inputs the data into the input port IN2 of the microcomputer 139. Thus, the detergent according to the weight of the laundry is supplied. The control signal is output to the output port OUT1 of the microcomputer 139 to operate the operation means 126 until

On the other hand, each time the operating means 126 is operated once, one solid detergent 70 stored in the solid detergent storage groove 92 of the detergent case 90 is introduced one by one, and the operation means 126 The projection 136a integrally formed at the lower portion of the spring sheet 138 and the pulling lever 136 in the space formed in the detergent feeding control lever 130 each time when the detergent feeding control lever 130 is pulled once. Since the elastic means 140 which is supported by the pressing means downward by the lower surface of the locking jaw 96, the detergent case 90 is moved by the pitch of one locking jaw 96 in the counterclockwise direction.

Therefore, the solid detergent 70 is sequentially introduced into the net container 44 in the detergent dissolution tank 42 one by one from the solid detergent storage groove 92 formed in the detergent case 90. In other words, since the detergent case 90 is rotated about the central axis 64 of the outer case 60, when the operating means 126 is operated once, one solid detergent storage groove 92 in the detergent case 90 is generated. ), One solid detergent 70 is dropped, and the next operation means 126 is operated once, so that one solid detergent 70 is dropped from the solid detergent storage groove 92 of the next compartment.

When the detergent passage hole 130a of the detergent injection control lever 130 and the detergent injection hole 62a formed in the bottom plate 62 of the outer case 60 coincide with each other, the detergent injection control lever 130 Since one side surface is in contact with the operating rod of the position detecting means 160, it detects that the detergent input control lever 130 has been normally operated and outputs the detection data to the input port IN2 of the microcomputer 139. At this time, when the microcomputer 139 blocks the control signal to the output port OUT1 and maintains the operation means 126 in an inoperative state, the detergent input control lever 130 is surrounded by the pulling force of the switching spring 132. It rotates counterclockwise about the center axis 64 of the case 60, and the rotation position is regulated by the stopper 138. As shown in FIG.

As described above, according to the solid detergent input device of the washing machine according to the present invention, the detergent case disposed in the outer case is interlocked about the central axis of the outer case in accordance with the operation of the solid detergent input means so that the solid detergent in the detergent case is The solid detergent stored in the storage groove is introduced into the net container disposed in the detergent dissolution tank, and the water supplied from the water supply pipe and the air supplied from the air injection hole of the accelerator are accelerated by the accelerator and supplied to the net container. It is configured to dissolve the solid detergent and supply it to the washing and dehydration tank, so that the appropriate amount of the solid detergent according to the amount of the laundry can be dissolved and supplied to the washing and dehydration tank under the control of the microcomputer at the same time, and the detergent thus supplied Laundry by a laundry dehydrator It devised a very practical that you can wash clean.
