Description

[Detailed description of the invention] (a) Technical field of the invention The invention relates to a two-tub washing machine in which a washing tub and a dewatering tank are installed separately and in parallel. However, it is washable.

(b) Prior art and its problems When washing in a spin-drying tank, it is necessary to provide a washing timer and a spin-drying timer individually or collectively in one to control the rotation of the spin-drying tank. The latter required complicated timers and was anyway expensive.

(c) Purpose of the present invention The purpose of the present invention is to reduce the cost of the timer by sharing the same washing timer used when washing in the washing tub when washing in the spin-drying tub.

(d) Structure and operation of the present invention In the present invention, a normally closed terminal of a selection switch is connected between the washing timer and the washing motor, and a selection terminal of the selection switch is connected between the washing timer and the dehydration motor. . Therefore, although the selection switch normally electrically connects the washing timer to the washing motor, during the selection operation it electrically connects the washing timer to the dewatering motor. As a result, the dehydrating motor is controlled by the washing timer to reversely drive the dehydrating tank at predetermined time intervals, and washing is performed in this dehydrating tank. In this way, the washing timer can be shared during washing in the dehydration tank.

(e) Embodiment of the present invention In the drawing, 1 is a two-tub washing machine in which a washing tub 2 and a dewatering tank 3 are arranged side by side in the machine frame, and a control box 4 is arranged horizontally at the rear of the upper part. In this box 4, there is a washing timer 5, a dehydration timer 6,
Washing water flow changeover switches 7, 8, a pair of selection switches 9, 9, and an interlocking switch 10 are installed, and the operation knobs 5 for each timer 5, 6 are mounted on the surface of the box 4.
1, 61, the push button type knobs 71, 81 of the washing water flow changeover switches 7, 8, and the common push button type knobs 91, 9 of the selection switches 9, 9 and the interlocking switch 10.
2 and a knob 11 for opening and closing a drain valve (not shown) of the washing tub 2. The push-button knobs 71, 81, 91, and 92 are arranged in a horizontal row.

The washing timer 5 has a main switch 54 and two reversing switches 52 and 53, each of which has a different cycle of switching at predetermined time intervals with pauses in between, and the dehydration timer 6 has a main switch 62. There is.

In addition, the washing water flow changeover switches 7 and 8 have knobs 71,
It is a two-way switch in which when 81 is pressed, one of the switches closes and the other opens. Further, the pair of selection switches 9, 9 are change-over type switches in which a normally closed terminal 93 and a selection terminal 94 are switched by knobs 91, 92. When the knob 91 is pressed, the knob 92 is raised and the normally closed terminal 94 is closed. Closed terminal 93,9
3 is closed, the selection terminals 94, 94 are opened, and when the knob 92 is pressed, the knob 91 is raised and the open/closed state is reversed. The interlocking switch 10 is interlocked with the operation of the knobs 91 and 92, and is in the same open/close state as the normally closed terminal 93. In addition, washing water flow selection switch 7,
8. The selection switches 9, 9 and the interlocking switch 10 are assembled as one switch mechanism (see the dashed line in the figure).

12 is a washing motor that drives a pulsator 13 in the washing tub 2; 14 is a centrifugal dewatering tank 1 in the receiving tank 3;
This is a dehydration motor that drives the 5.

Here, the dehydration tank 14 has a dehydration hole only on the upper circumference side, or can store water in the tank 3 so that water can be stored therein.

Next, the electrical connection will be explained. First, the main switch 54 of the washing timer 5 and the main switch 62 of the dehydration timer 6 are connected to the power source via the interlocking switch 10. The above main switch 54
The washing water flow changeover switches 7 and 8 are connected to the main switch 62, and the dewatering motor 14 is connected to the other main switch 62 via a normally closed safety switch 16 which is opened when the dehydrating top cover is opened. One side of the washing water flow changeover switches 7 and 8 is connected to one of the reversing switches 52 and 53, and the other side is connected to the other of the reversing switches 52 and 53, respectively. The inverting switches 52 and 53 have respective inverting terminals connected to a pair of selection switches 9 and 9 separately. The normally closed terminals 93, 93 of the selection switches 9, 9 are connected to the washing motor 12, and the selection terminals 94, 94 are connected to the dewatering motor 14, respectively.

To explain the operation, first, when washing in the washing tub 2, one of the washing water flow changeover switches 7 and 8 is pressed and the washing timer 5 is set to a certain time. For example, when the washing water flow selector switch 7 is closed, the washing motor 12 is reversed in a long period according to the reversal cycle of the reversal switch 52, and the pulsator 13 is
Invert. When the switch 8 is closed, the washing motor 1 is activated according to the reversal cycle of the reversing switch 53.
2 is reversed in a short period. That is, in the case of switch 7, there is a so-called strong water flow, and in the case of switch 8, there is a so-called weak water flow.

If the dehydration timer 6 is set during this washing, power can be supplied to the dehydration motor 14 via the interlock switch 10, so that the dehydration tank 15 can be continuously rotated in one direction at high speed to perform dehydration.

When washing small items that are easily damaged in the dehydration tank 15, store water in the dehydration tank 15, or continue to supply water, and turn the selection switch 9, 9 by operating the knob 92.
, close the selection terminals 94, 94, and set the washing timer 5. At this time, the interlocking switch 10 is also opened in conjunction to open the circuit of the dehydration timer 6. In this manner, water and laundry are moved within the dehydration tank 15 by centrifugal force, or a water flow is generated by the cap at the inner bottom, and this state is intermittently repeated. As a result, laundry items such as small items that are easily damaged can be washed in a so-called soft manner.
If the water flow in the dehydration tank 15 is too weak, a cylindrical body is inserted into the tank to generate the water flow. Regarding the washing water flow changeover switches 7 and 8, it is desirable to keep the short cycle switch 8 closed so that the water in the tub does not run out due to centrifugal force.

Intermediate and final dehydration can be performed in the tank as is by pressing the knob 91 to return the selection switches 9, 9 and the interlocking switch 10 to their original open/closed states and setting the dehydration timer 6.

(f) Effects of the present invention According to the present invention, when washing clothes in a spin-drying tank, the timer for washing in the washing tank is also used as a timer, so that the expense required for a timer can be eliminated.
