Description

[Detailed Description of the Invention] Technical Field> The present invention is applicable to washing, rinsing, and spin-drying devices that are capable of washing, rinsing, and dehydrating. The present invention relates to washing machines including those capable of only one of washing, rinsing, and dehydration.

<Prior art> In conventional washing machines, the washing, rinsing, and spin-drying times are displayed using a running time display dedicated to each stroke, and each display can be lit for 7 consecutive times or flashed continuously. This is done by changing.

However, in this configuration, since there are two types of display states, it is insufficient to grasp the elapse of the remaining operation time, and there is little benefit to the user. In addition, 1) the configuration of displaying the remaining operating time in the Denotal system has the drawback that it increases costs.

<Objective> An object of the present invention is to provide a washing machine in which the remaining time can be fully grasped by dividing the operating time into three or more types of display states on the display.

<Example> Embodiments of the present invention will be described below with reference to the drawings.

First, in the block diagram of FIG. 1, there is a dehydration sensor 3 that detects water droplets scattered from the dehydration hole of the dehydration tank, a comparison circuit that compares the output water droplet signal (voltage signal) with a comparison level,
1 and a washing/rinsing time setting switch 5 for setting the continuous operation time of the washing (dewatering) motor 5 (single-tank fully automatic washing machine, which can also be used as a motor for W Iso). and an automatic control circuit B that automatically controls the motor 5 via its drive circuit 8 based on the dehydration state detection circuit A, the output signal of the washing/rinsing time setting switch 6, and the signal of the timer 7. I'm in the middle of the day.

The automatic control circuit B includes a program/fixed data memory RAMI (1, the timer 7, a CPU II consisting of a microprocessor, and a 110 unit (input/output unit)).
It consists of 12. 13 is a start switch. Further, a relay is used in the drive circuit 8, and the dewatering motor 5 is rotated and stopped at its contact 8a. 5a, 5b
is a winding of the motor 5, and 5c is a running capacitor.

In the present invention, a time setting device is provided for setting the operating time of at least one of the washing ii1, rinsing, and dewatering steps, and the time setting device is provided.

Displays the remaining time in the set operating time.

The automatic control circuit B is provided with an ED display E and is configured to also control the display E based on the output signal of the time setting device. By sequentially switching to the periodic blinking state F2, the medium periodic blinking state F3, and the short periodic blinking state F4, the operating time of one stroke is divided into at least three lighting/blinking states and the remaining time is displayed on the display E. It is configured.

The time setting device is composed of the washing/rinsing opening setting switch 6 and a dehydration state detection circuit A.

Next, the washing/rinsing operation time is input by the user into the washing/rinsing opening setting switch 6 based on the type and amount of laundry, and the spin-drying completion time T2. (Dehydration operation time) is automatically set by 4aJr% of the dehydration state detection circuit A and automatic control circuit B. Then, the washing (dewatering) motor 5 is driven by the output signal of the automatic control circuit B via the drive circuit 8. At the same time, timer 7 counts time. As shown in Fig. 2, when the operating time of each stroke is 12, the initial fixed time opening T1 causes the indicator E to be in the continuous lighting state F1.
shall be. Next, the display E will be in a blinking state. At this time, for example, the blinking cycle of the display E is switched to a large cycle blinking state F2, a medium cycle blinking state F3, and a short cycle blinking state F4 in FIG. In other words, the remaining operating time (T2-TI)
is divided into three equal parts, and the blinking period becomes smaller as the remaining time decreases, such as high, medium, and small. Therefore, the user must ensure that the remaining operating time is equal to or greater than /2 in the continuous lighting state F1, that the remaining operating time is 1/2 to 1/3 in the large period flashing state F2, and that the remaining operating time is 1/2 to 1/3 in the medium period flashing state F2. 1/3~1
/6, and the remaining time is 1/6 in short cycle blinking state F3.
It can be determined visually that it is 6 or less.

Next, a second embodiment of the present invention will be explained with reference to FIGS.
There are 1.2, ...... integers) LIE D, and among the washing, rinsing, and spin-drying times (including those set by manual timers), for example, washing time or 1

It should be noted that the present invention is not limited to the configuration of the above-mentioned embodiments, and it goes without saying that many modifications and changes can be made to the above-mentioned embodiments within the scope of the present invention.

As is clear from the explanation in "Effects", the present invention is provided with a time setting device for setting the operating time of at least one of the washing (rinsing and dehydration steps); A display device is provided to display the remaining time in the set operating time, and an automatic control circuit is provided to control the display device based on the output signal of the time setting device, and the automatic control circuit is configured to turn on at least three or more lights.・It is constructed so that the operating time of one stroke is divided into blinking states and the remaining time is displayed on the display.

Therefore, according to the present invention, there is an excellent effect of providing a washing machine in which the remaining time can be fully grasped by dividing the operating time into three or more types of display states on the display.
