Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a clothes dryer having a lid for putting in clothes on the outer peripheral surface of a drum for storing clothes.

2. Description of the Related Art As shown in FIG. 4, the configuration of a conventional drum fixed position control device for a clothes dryer is such that at the end of drying, the operation control section 2 inputs a rotational position detection signal from the rotational position detection means 8, and then After electromagnetic braking and reverse driving of the motor 3 are repeated a certain number of times by the motor drive unit 10, the drum lid 6 is stopped at a predetermined position. This drum 4 rotates in the horizontal direction, and has a drum lid 5 on its outer periphery for loading and unloading clothes, so that when the drum 4 is stopped at a predetermined position and the drum lid 5 is opened, the clothes are securely removed. I make it so that I can take it out.

Problems to be Solved by the Invention In conventional clothes dryer drum position control,
Motor 3 for stopping drum lid 6 at a predetermined position
Since electromagnetic braking and forward/reverse driving are repeated, the drum lid 6 can be stopped at a predetermined position in a short time.
During electromagnetic braking, the electromagnetic sound and vibration noise from the motor are transmitted to the drum, etc., causing the product to vibrate and making a high noise when stopped. Therefore, the drum fixed position control at the end of the drying process is not performed at the fixed position during the temporary stop. If the fixed position control is performed using a drum fixed position control sequence method that stops the drum lid 6 at a predetermined position without electromagnetic noise or vibration noise from the motor using a different control, this lower ram fixed position control will continue until the end of the drying process. The problem was that the position control sequence could not be confirmed.

In view of the above problems, it is an object of the present invention to easily confirm the drum fixed position control sequence at the end of the drying process using special input setting means.

Means for Solving the Problems To achieve this object, the present invention provides a drum that rotates around the horizontal direction, a drum lid provided on a part of the outer peripheral surface of the drum for loading and unloading clothes, and a drum lid that is provided on a part of the outer peripheral surface of the drum, and a rotational position pressure detection means for detecting the rotational position of the drum; an operation control unit that receives the rotational position detection means and a pause switch as input; a motor that drives the drum; and a rotational position detection means for detecting the rotational position of the drum; and a motor drive unit that performs drive control of the drying process, and the operation control unit intermittently controls the drive of the motor to turn on and off the rotation of the drum at a low speed so that the drum reaches a predetermined position. is detected by the rotational position detection means, the motor is turned OFF, and a drum fixed position control sequence is executed to control the drum lid to stop at a predetermined position, and after setting by the special input setting means, the drum lid is temporarily stopped during operation. The switch is configured to control the drum lid to stop at a predetermined position according to the drum fixed position control sequence.

Operation With this configuration, by operating the special input setting means, it is possible to easily confirm or inspect the drum position control sequence at the end of the drying process.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows the configuration of a drum fixed position control device for a clothes dryer according to an embodiment of the present invention, and FIG. 2 shows a flowchart of a drum fixed position control method according to an embodiment of the present invention.
FIG. 3 shows a waveform of energization to the motor during drum fixed position control in the embodiment.

First, in FIG. 1, the power supply section 1 causes the operation control section 2 to
．． Power is supplied to the motor 3. Furthermore, while the drum 4 is rotating, a predetermined position pressure detection signal is input to the operation control section 2 by the proximity switch 6, magnet 7, and rotational position detection means 8 every time the drum lid 6 passes a predetermined position. The operation control unit 2 is a reverse operation control unit 2 that controls the reverse direction of the motor 3! L, a forward rotation operation control section 2C that controls the forward rotation direction of the motor 3, and a reverse rotation operation control section 2& that controls the motor 3 in the forward rotation direction.
It has electromagnetic braking means for applying electromagnetic braking to. Further, the motor drive section 1o is the reverse operation control means 2! of the operation control section 2! A reverse rotation drive section 10b that controls energization to the main winding side of the motor 3 based on the L signal, and a forward rotation operation control means 2.
The forward rotation movable part 10 controls the energization to the auxiliary winding of the motor 3 using the signal C! It has L. Further, the electromagnetic braking control means 2b controls the reverse rotation operation control means 2a, and the reverse rotation driving section 1ob applies electromagnetic braking by energizing the auxiliary winding of the motor 3 in a short pulse form.

Here, in FIG. 2, after turning on the power switch, press the start switch (step 13) to start drying the clothes, and when the signal from the drying end sensor 11 is input to the operation control section 2 (step 15), the drying operation starts. When the process is completed, the drum lid 5 is stopped at a predetermined position. The drum fixed position control sequence at this time is to stop energizing the motor 3 for a certain period of time (Step 16). After the drum 4 has stopped, the main winding of the motor 3 is intermittently energized (Steps 17 and 18). In this case, the motor 3 is energized for a short time (for example, 0.1 seconds),
After moving the drum 4 a little, after the drum 4 has stopped (for example, after the motor 3 has been turned off for 0.5 seconds), the motor 3 is repeatedly energized for a short period of time, so that the drum lid 6 is in the specified position. Then, the rotational position detection signal turns ON (
Step 1), the drum lid 5 finally stops securely at a predetermined position.

On the other hand, if the test switch is ON when the power switch is turned on, the special input setting means 3o enters the inspection mode of the drum fixed position sequence after drying is completed (step 12); The start switch is pressed (step 20), and drying operation is started (step 21).

If you operate the pause switch while driving (step 22)
), step 16 to proceed to the step at the end of the drying process.
), the drum fixed position control sequence is performed, and when the drum lid 5 reaches the predetermined position, the rotational position detection signal turns ON (
Step 16), the drum lid 6 stops at a predetermined position.

In this example, an inspection switch was used as the special input setting means, but the
The power switch may be turned on while a plurality of operation switches (timer 20 minutes, timer 60 minutes, thick tooth, standard course, ironing course, heater switching, etc.) are pressed at the same time.

In this case, there is no need to provide a dedicated test switch in 49, and the special input setting state can be set in the finished product state.

In addition, the present invention is not limited to the embodiments described above or shown in the drawings, and may be implemented with appropriate modifications within the scope of the gist. In the normal sequence, the drum position control sequence cannot be confirmed until the end of the drying process, but the drum position control sequence can be easily confirmed and inspected using the special input setting means. The inspection in the product manufacturing process can be simplified and shortened, and the effect is extremely large.
