A display corresponding to the remaining time is flickered to display the elaspe of time in this display.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timer, and is particularly used in electric washing machines for washing household clothes, dishwashers for washing tableware, etc. This relates to a configuration that also displays.

Conventionally, time switches for electric washing machines and the like have generally been clockwork-type mechanical time devices that mechanically open and close electrical contacts, and their display devices have been simply numerical scales. Therefore, there is a drawback that the operability is poor and it is very difficult for the user to understand that the timer is operating every moment.

The present invention provides a timer that eliminates the above-mentioned conventional drawbacks and greatly improves display function and operability,
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows an example in which a timer according to the present invention is mounted on an electric washing machine, and an outer shell 1 of the washing machine is composed of a casing 2, a top lid 3, and an operation panel 4. Inside the housing 2, a washing tub, a dehydrating tub, a washing machine, a pulsator, etc. are arranged as is well known.

FIG. 2 shows an enlarged view of the operation panel 4, which is equipped with input switches and a display. In detail, there is a water flow selection switch 5 that changes the strength of the water flow in the washing tub, a stop switch 6 that temporarily stops the washing timer, a washing switch 7 that sets the washing time and operates the washing timer, and a washing switch 7 that sets the rotation time of the spin-drying tub. and a dehydration switch 8 that operates a dehydration timer, a water flow display device 6o, and a washing time display device 7.
0, it has a dehydration time display device 8o. Each of the display devices 60, 70, and 80 is composed of a light indicator, and when the water flow selector switch 6 is set to ``strong water flow,'' the indicator corresponding to the character ``strong'' on the water flow display device 6o emits light. do.

When the washing time is set to 10 minutes with the washing switch 7, the indicator corresponding to the number "10" on the washing time display device 7o lights up. Further, when a certain time is set with the dehydration switch 8, the indicator corresponding to this time emits light. A light emitting diode or a liquid crystal display is suitable as the display for each of the display devices 50, 70, and 80 described above.

FIG. 3 shows an example of a display method of the washing time display device 70 of the washing timer. First, in the initial state when the power switch is turned on, the display does not light up and the timer does not operate. Next, if you keep pressing the washing switch 7, the short-time display will start with a, then b, then c.

For example, when the display d in the third garden lights up, when the washing switch 7 is released, the display d will blink and the washing will continue for the time indicated by the display d. .

That is, by using the washing switch 7, the washing timer can start counting at the same time as setting the washing time. In the washing time display device 7o, the display corresponding to the remaining time blinks to indicate the passage of time, and the situation is shown in FIG. 3(B).
(It changes like Q.

In Figure 3 (q), the display corresponding to the remaining time blinks, and then the display a (remaining time, for example, 3 minutes) also lights up.Finally, the lit display disappears. The blinking of the display is performed in the same way in the dehydration time display device 80, so I will explain it here.

FIG. 4 shows another example of the display form. To set the time shown on the display d (for example, 10 minutes) when the washing switch is completed, press the washing switch 7 four times, a, b, c,
The displays light up in the order of d, and when the washing switch 7 is released, the display d remains lit and the displays c, b, a, c,
B and a blink in that order. In other words, Fig. 4 (A), (
B) and (C) are repeated in sequence, and at the remaining time C, display d goes out, display C remains lit, and b
, a, b, a, the display repeats blinking in this order. Additionally, as a method of setting the washing time using the washing switch 7, as mentioned above, when the washing switch 7 is held down, the display lights up in the order of a, b, c, d, e, f. and then all indicators disappear, then a, b again
, c, d, old, etc. are lit in this order.

FIG. 5 shows a block diagram of the timer, and the input switch 40 consists of the water flow changeover switch 6, stop switch 6, washing switch 7, and dewatering switch 8 described above. The input switch 40, a timer consisting of a clock, a counter, a time setting circuit, etc., a control device 9 for controlling input and output, and each of the aforementioned display devices 50, 70, and 80 consisting of a light emitting diode. a washing motor 12 having a display device 1o having a phase advance capacitor 11;
A timer is constituted by an output switching device 14, 15, 16, such as a bidirectional Zyristor, which reverses the rotation of the dewatering motor 13.

The control device 9 can be easily realized by a programmable LSI such as a microcomputer, which has become widely used these days.

As described above, according to the present invention, a signal from an input switch such as a pushbutton switch is input, an output switching device such as a display device and a bidirectional thyristor is used as output,
In addition, a control device having a timer and an input/output control section is provided, and in particular, a plurality of parallel display devices forming a display device display the set time, the remaining time of the stroke, and the timer operation status, respectively. The set times are displayed on an indicator such as a light emitting diode for each maximum set time, for example, 3 minutes, 5 minutes, 7 minutes, and 10 minutes for washing time.

They are arranged in parallel every 15 minutes, improving operability.

In addition, the display of the dehydration time is the same as the washing time, and the frequently used setting time of the dehydration time is usually 0.5
minutes, 1 minute, 3 minutes, and 5 minutes, and in this case, it is sufficient to provide four indicators.

The time can be set automatically by continuing to operate the input increment, and by operating the switch once, the time can be increased by one step.
