Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a control device for a clothes dryer that is provided with a clothes input section on the outer peripheral surface of a drum for storing clothes.

2. Description of the Related Art As shown in FIG. 3, the configuration of a conventional drum control device for a clothes dryer is such that when an input section 1 is set to stop a drum 6, an operation control section 3 is activated by a motor drive section 5. 2. The drum 6 is rotated at a low speed by performing energization control as shown in FIG. , the motor 11 was stopped. Further, after the drum 6 rotates at a low speed, if the drum lid 7 does not reach a predetermined position, it stops at an arbitrary position.

Problems to be Solved by the Invention In such a conventional drum control device for a clothes dryer, when the amount of clothes exceeds the rated value or when the voltage applied to the motor 11 decreases, the torque of the motor 11 is However, the drum 6 stops moving during low-speed rotation and does not reach a predetermined position, causing the motor 11 to continue operating for a long time. -! Another problem was that the user did not know that there was an abnormal condition.

In view of the above problems, the present invention immediately turns off the motor when the drum cover does not reach the predetermined position within a certain period of time, and clearly informs the user that the drum cover has not stopped at the predetermined position. The purpose is to inform.

Means for Solving the Problems In order to achieve the above objects, the present invention provides a drum that rotates around a horizontal direction, a drum lid provided on a part of the outer peripheral surface of the drum for loading and unloading clothes, and a rotational position detection means for detecting the rotational position of the drum; an operation control section that receives the rotational position detection means as an input; a timer section that operates according to a signal from the operation control section; a motor that drives the drum; The operation control section operates the timer section when the rotation of the drum is stopped, and stops the rotation within a certain period of time. If the predetermined position detection signal is not detected by the position detection means, the operation control section determines that there is an abnormal state and turns off the motor;
The notification is configured to be performed by the notification means.

Effects With the above configuration, if the drum lid does not reach the predetermined position within a certain period of time, the motor can be immediately turned off, and the user can be clearly notified of the abnormal condition using a buzzer or an indicator light.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2. The drum control device for a clothes dryer in this embodiment has a power supply section 2, an operation control section 3. Power is supplied to the motor 11. Further, while the drum e is rotating, a predetermined position detection signal is input to the operation control section 3 by the proximity switch 8, magnet 9, and rotational position detection means 4 every time the drum lid 7 passes a predetermined position. Here, when the stop of the drum 6 is set by the input unit 1, the operation control unit 3 controls the motor 11 as shown in FIG. control. FIG. 2 & is a predetermined position detection signal, and an ON signal is input to the operation control section 3 every time the drum lid T passes a predetermined position.

Here, after the stop of the tram e has been completely set by the input section 1, when the predetermined position detection signal of the turtle in FIG. The motor 11 is operated intermittently. Normally, the drum lid 7 reaches the predetermined position again during intermittent operation, the predetermined position detection signal turns ON, the motor 11 is turned off, and the drum lid 7 stops at the predetermined position. If the voltage applied to the motor 11 decreases, the motor 11 will lock during intermittent operation and the drum 6 will not move.
has not reached the predetermined position. In such a case, in order to notify the user of the abnormal condition at an early stage, the timer unit 12, which is operated simultaneously with the predetermined position detection signal turning ON, as shown in FIG. If the predetermined position detection signal is not generated again even after 15 seconds have elapsed since then, that is, if the drum lid 7 does not reach the predetermined position, the motor 11 is turned off and an abnormality is notified by the notification means 13 such as a buzzer or indicator light. . Therefore, the user can clearly confirm that there is an abnormal state.

Effects of the Invention As is clear from the above embodiments, according to the present invention, if the drum is not moved to a predetermined position within a predetermined time after a stop command, an abnormality is determined. To control a drum cover to stop at a predetermined position when the applied voltage decreases, and even if the drum stops at a place other than the predetermined position, the user can clearly confirm the abnormal state by a notification means. In addition, the motor can be unlocked in a short time, improving safety.
