Description

[Detailed Description of the Invention] B) Industrial Application Field The present invention relates to a control device for a washing machine that is capable of reserving the start or end time of a washing operation consisting of washing, rinsing, and spin-drying steps. .

(b) Conventional technology This type of washing machine is disclosed in Japanese Patent Application Laid-Open No. 56-45696, and if you reserve a finish time, the current time is compared with the time obtained by subtracting the operating time from the finish time. The system then starts operation when a match is found.

PM Problems to be Solved by the Invention However, this reserved operation is the same as normal operation without reservations, and as the washing and rinsing reversal cycles become shorter in recent years, the motor (pulsator) may run more frequently while sleeping. The rising sound became annoying.

Therefore, there is a proposal to automatically shift to a reversal cycle with a long rest time during scheduled driving to ensure a good night's sleep. However, the reserved time does not necessarily coincide with bedtime; for example, if you work late at night and want to do the laundry during the day, you may want to have the laundry run in the morning when people are already awake. In this case, it is not necessary to use a reversal cycle with a long pause time, but rather it is better to perform the washing operation in a short time.

The present invention aims to control scheduled operations in an extremely rational manner by automatically specifying and executing an appropriate washing operation according to the scheduled time.

B) Means for Solving the Problems The solution according to the present invention includes a time reservation means for reserving the start or end time of a washing operation consisting of washing, rinsing, and spin-drying steps, and a time reservation means for reserving the start or end time of a washing operation consisting of washing, rinsing, and spin-drying steps, and a time reservation means for reserving the start or end time of a washing operation consisting of washing, rinsing, and spin-drying steps; a reservation time determination unit that determines whether the reservation time is the same, an operation designation unit that designates normal laundry operation or nighttime laundry operation according to the determination result of the reservation time determination unit; This configuration includes a start time determination section that determines when the start time of the operation has arrived, and an operation control section that causes the washing operation specified by the operation specification section to be executed at the start time.

(e) Function When the start or end time of the washing operation is reserved, the determination unit determines whether the reserved time is within bedtime.

For example, if the washing operation times overlap between 10 p.m. and 7 a.m., specify a night washing operation that includes a reversal cycle with long downtimes to avoid frequent pulsator (motor) startup noise. do. And if you are outside of this time zone.

To specify a normal washing operation, which has a short downtime and a sufficiently short total operating time compared to a night-time operation. In other words, reserved driving is performed slowly and with suppressed harsh sounds during bedtime hours, and is quickly performed as usual at other times, and this can be automatically separated by simply setting the reserved time.

(f) To explain based on the drawings of the embodiment, in Fig. 3, the sequence of water supply, soaking if necessary, washing, draining, dehydration, water supply, rinsing, draining, dehydration, water supply, rinsing, draining, and final dehydration is shown. The machine frame of a fully automatic washing machine that sequentially performs the following processes (inside the IJ, there is an outer tank (2) and a porous washing and dehydrating tank (3), and the inner bottom of the dehydrating tank (3) has a large A radial-shaped pulsator (4) is disposed on the outer bottom surface of the outer tank (2).
), a motor (5), a pulley belt (6), and a speed reduction mechanism (7) are installed.

Further, a drainage channel (9) is connected to the outer tank (2) through a drainage solenoid valve (8). Water is supplied through a water supply channel αV via a water supply solenoid valve α■. Machine frame (
1) A control device including a microcomputer (hereinafter referred to as microcomputer) (13) for controlling the entire fully automatic washing operation is built into the control box U at the top of the machine. As shown in the figure, the operation keys and the second indicator light (L
ED) is provided. Microcomputer (2) is ROM, RAM
, CPU, and Ilo, and as shown in Figure 1, a clock (5), a power supply circuit 06), a reset circuit (1'?), and a water level sensor (one on the regular signal generation means side). Connect, start key ■, stop key (21)
, reservation key (support), time key (2), time adjustment knob (
goods) (constituting the time reservation means together with the reservation key), digital time display■, various indicator lights such as LEDs (a)
..., buzzer @, output to each load's drive circuit ■.

As shown in Fig. 1, the microcomputer α performs operation control, including an operation discrimination unit (branch), a current time counter ■, an operation control unit Oυ, a reservation time discrimination unit (branch), a drive specification unit country,
It comprises a start time calculation section (to), a reservation content storage section (to), and a start time determination section (to).

Next, the operation will be explained based on the flowchart in Fig. 4. When the operation discrimination section ■ discriminates normal operation with no reservation memory, the time display will display the contents of the current time counter ■ as is. If the start key ■ is operated, the normal washing operation is executed by the operation control section C1υ. This normal washing operation is a cycle in which the pulsator (motor) is intermittently turned left and right with a short pause of about 0.5 seconds between each washing and rinsing process, and the total operating time is After about 20 minutes, it happened.

Next, the reservation of the driving end time is made by specifying the reservation mode by operating the reservation key (2), and is determined by the determination section. In this mode, if a reservation has been made in advance, the reservation time will be displayed on the display ■, and you can check the change time on the display using the time adjustment knob that can be freely rotated left and right. When the reservation time (end time) for reserving the end time is set, the reservation time determination unit (2) determines whether this time overlaps with the bedtime period. Then, if they overlap, the operation specifying section (to) of the microcomputer (to) specifies a night washing operation, and if they do not overlap, a normal washing operation. Such nighttime washing operations reduce complaints by reducing the rising noise by running a cycle in which the pulsator (motor) is reversed with a long pause of about 6 seconds between the washing and rinsing steps. , since it is reversed the same number of times as normal operation, the total operation time is 5
It was extended to about 0 minutes. After making this adjustment, press the start key■
When operated, the start time calculation unit (to) on the microcomputer side calculates the start time based on the reservation time and the designated operation, and stores it in the reservation content storage unit (to). Furthermore, if there is a delay in operating the start key (A) after adjustment, the indicator light, buzzer,
The user is prompted to operate the start key using an audio device or the like.

If you want to know the reserved time after the reservation is completed, press the reservation key (base) and the display (c) will appear for only 5 seconds.

When setting the current time, change the mode by operating the time key (2), and adjust the time using the time adjustment knob while looking at the time displayed on the display (G).

The current time counter will keep ticking according to the adjusted time, turn off the power switch (not shown), or turn off the power automatically after the operation is finished! When the disconnection means operates, the reserved time is erased, but a signal can be outputted from the clock signal generation means α to the counter that clocks the current time.

Therefore, whether or not there is memory in the reservation content storage unit (to) is determined by the driving determination unit, and if there is memory, the start time determination unit (to) will check the calculated start time and current time counter. ■
The content is compared to see if they match. If they match, the operation control unit (9) executes the washing operation specified by the specified operation country.In this embodiment, one type of washing operation is normal washing operation, but the operation control unit (9) executes the washing operation specified by the specified operating country. It is also possible to add variety by adding keys to change the time and number of times for each stroke.

Although the sleeping time period was set as 10:00 pm to 7:00 am, this can also be changed arbitrarily within an appropriate range.

(G) Effects of the Invention According to the present invention, the normal washing operation or the night washing operation is automatically specified and executed depending on the reservation time, so that the noise is generated even if the time is long at night. It is possible to automatically perform highly rational control to prevent this from occurring and finish washing in a short time during the day just by setting a reservation time.
