Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a control device for a washing and dehydrating machine with a timer function that allows the user to complete washing at a time desired by the user and to set a washing end time. be.

2. Description of the Related Art A conventional control device for a dehydrating/washing machine equipped with a timer generally performs control through the process shown in FIG. That is, if the user wants to complete the laundry at a desired time, the user opens the lid of the washing machine in step 10, puts the laundry into the tank in step 11, closes the lid of the washing machine in step 12, and in step 13. Set the washing end time. After completing the operations from step 10 to step 13 above, it is determined in step 16 whether it is time to start washing, and if it is the time to start washing, water is supplied in step 17, stirring is performed with the pulsator in step 18, and step 19 is carried out. Then, in step 2°, it is determined whether the lid of the washing machine is open or closed. If the lid is closed, the tank is rotated in step 21, and the washing machine starts dewatering operation. However, if it is determined in step 2Q that the lid is opened, a loop is formed in which the process returns to step 20 until the lid is closed. Therefore,
Unless the lid of the washing machine was closed, the washing machine would pause at the state before spinning.

Problems to be Solved by the Invention In such a conventional configuration, when a user attempts to finish washing at a desired time, he forgets to close the lid in step 12, sets the washing end time, and leaves the washing machine. When the washing machine is put away, it is not possible to move on to the spin-drying operation, and the washing machine cannot be operated for many hours afterwards unless the lid is closed. Therefore, when the user judges that the laundry has been completed at the desired time and goes to take out the laundry from the washing machine, there is a problem in that the laundry is not yet completed.

The purpose of the present invention is to solve the above-mentioned conventional problems and add a function to quickly inform the user of any condition that may impede the automatic process progress of a washing machine that also serves as a dewatering machine, thereby ensuring that washing is completed at the set time. .

Means for Solving the Problems In order to solve the above problems, the control device for the dehydrating and washing machine of the present invention determines that the lid is open after the end time is set by the washing end time setting means. In this case, the configuration includes a control means for notifying the user of the abnormality by at least one of the display means and the notification means.

Function According to the above configuration, if the lid is opened with the bathing end time set, the user's visual and auditory senses can be appealed to by at least one of the abnormality display and abnormality notification means. This prevents the user from forgetting to close the lid, and allows the user to reliably complete washing at the desired time.

Embodiment A control device for a washing and dehydrating machine equipped with a timer according to an embodiment of the present invention will be explained with reference to FIG.

In Fig. 1, in order to prevent water from splashing during washing, washing from falling out during spin-drying, and injuries caused by the tank circuit during spin-drying, a lid 1 is provided to cover the part for putting clothes into the tank. The opening/closing of the lid is determined by the lid opening/closing determination means 2. The washing end time setting means 3 for setting the washing end time and the lid opening/closing determination means 2 are inputted to the control means 8, and the control means 8 controls the display means 4 and the notification means for displaying and informing the progress and settings of the washing machine. 5. Controls a drain valve drive device 6 for draining water from the tank and a tank drive device 7 for driving the tank. Further, the lid opening/closing determination means 2, the washing end time setting means 3, and the control means 8 are constituted by a microcomputer 9.

The operation of the above configuration will be explained based on FIG. 2. The user wants to finish washing the laundry at a desired time several hours later, so in step 10, the user opens the lid 1 of the washing machine, and in step 11, throws the laundry into the tank of the washing machine. Next, in step 12, the lid 1 of the washing θ machine is closed. Next, in step 13, a desired washing end time is set.

After completing the above operations, the control means 8 shown in FIG.
If you have forgotten to close the lid 1, in step 15, at least one of the display means 4'' and the notification means 6 performs an abnormality display operation or an abnormality notification operation and closes the lid 1. The user notices that he has forgotten to close the lid 1 through his visual and auditory senses. Due to the abnormal condition, the user realizes that he has forgotten to close the lid 1 and closes the lid 1. When the lid 1 is closed, the control means 8 determines in step 16 whether or not it is time to start washing. If the start time has not yet arrived, the process returns to step 14, and the open/closed state of the lid 1 is determined again.If the start time has come, the control means 8 controls the water supply in step 17, the stirring in step 18, and the step In step 19, water is drained, and in step 20, the open/closed state of the lid 1 is determined, and in step 21, the tank is rotated to proceed to the next step, so that the washing is completed at the time desired by the user.

Next, after the user has set the laundry end time but the laundry start time has not yet arrived, the user opens the washing machine lid 1 again for reasons such as adding laundry or changing laundry. The control process when this operation is performed will be explained based on FIG.

In this figure, the same reference numerals as in FIG. 2 indicate the same contents. When the user sets the washing end time in step 13 with the lid closed in step 12, the process proceeds to step 22, where the open/closed state of the lid is determined again. If the lid is closed at this time, the process proceeds to step 16, and it is determined whether or not the washing start time has arrived. If the start time has not come, the process returns to step 22, and the open/closed state of the lid 1 is determined again.

While the control means 8 is performing the loop from step 22 to step 16, if the user opens the lid 1 again and inserts or changes laundry, the control means 8 controls the lid 1 in step 23. Determine whether or not the opening time of step 1 has passed for a certain period of time, and if the certain period has not elapsed, proceed to step 22.
Returning to step 16, the open/closed state of the lid is determined, and if the lid is closed, the process advances to step 16. If a certain period of time has elapsed, it is determined that the user has forgotten to close the lid, and the control means 8 performs step 2.
At step 4, at least one of the display means 4 and the notification means 5 performs an abnormality display operation or an abnormality notification operation to appeal to the user's visual and auditory senses that the user has forgotten to close the lid 1.

As described above, in this embodiment, when the washing end time is set, it is possible to judge whether the user forgets to close the lid and obstructs the progress of the washing process, and the user can complain. This allows the user to reliably complete laundry at the desired time. Furthermore, when the user opens the lid again before the washing start time, it is also possible to complain to the user that he/she forgot to close the lid.

Effects of the Invention As described above, according to the present invention, after the end time is set by the washing end time setting means, when the lid opening/closing determination means determines that the lid is open, the display means or the notification means is activated. Since the abnormality display or abnormality notification is performed by at least one of the means, it is possible to prevent forgetting to close the lid, to smoothly proceed with a series of processes such as washing, rinsing, and spin-drying, and to ensure that the laundry is completed at the end time. You can finish washing.
