Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides dryness notification once at a low drying rate;
The present invention relates to a notification device for a dryer that restarts the process when the dryer is completely dry.

In conventional dryers, the completion of drying is notified only when the dryer is completely dry. I guess you took out your clothes at this time.
The clothes are now dry, which is not desirable when ironing them.

In order to solve such conventional inconveniences, the present invention provides a condition in which clothes have moisture suitable for ironing (drying rate eO ~ 1).
00%) and complete drying (drying rate 102-104%). Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In the block diagram shown in FIG. 1, a sensor 1 is composed of a pair of electrodes provided in a rotating drum, for example, and detects the electrical resistance of clothing by applying a voltage.
Enter. The dryness detection means 2 is a circuit that receives the output of the sensor 1 as an input and outputs an output if, for example, the period during which the resistance value of the clothing is greater than the set value is longer than a predetermined time, and the output is sent to the delay means 3 and the first is input to the notification control means 4 of. The delay means 3 consists of, for example, a timer IC, and measures the time from the output of the dryness detection means 2 until complete drying, and its output is input to the second notification control means. The first notification control means 4 is configured to intermittently send a signal to the notification means 6 only during the pulse generation period after the output from the dryness detection means 2 is input, even if it is not composed of a bell pulse generation circuit and a multivibrator. be. The second notification control means 6 is configured to continuously send a signal to the notification means 6 only during the pulse period after receiving the output from the delay means 3, such as a pulse generating circuit. The notification means 6 is, for example, a buzzer.

The specific circuit shown in FIG. 2 will be described in detail. Reference numeral 7 is for detecting the electrical resistance of clothing provided inside the rotating drum.

The electric board% constitutes a buzzer 1. The dryness detection means 2 includes an electrode 7
The input is the change in resistance between the two, and the output is L while the cloth is wet.
ow, but when it detects that the drying rate is 90 to 100 inches, the output is set to High. The delay means 3 delays the output A of the dryness detection means 2 for a predetermined period of time to make the output High.
Make it h.

Next, the first notification control means 4 will be explained. 8 is a resistor, 9 is a capacitor, and 10 is an Set B to High and then to Lo again.
Return to w. 12, the multi-vibrator 12 oscillates only while it is at High O, and when B is at Low, the output C of the output circuit 13 of the multi-vibrator 12 also becomes Low.

Next, the second notification control means 6 will be explained. It consists of a pulse generation circuit, resistors 14. Capacitor 1 B
, and an XOR circuit 16. In this operation, similarly to the pulse generating circuit 11, after the input becomes High, the output E becomes High for a certain period of time, and then returns to Low again.

Next, regarding the notification means 16, 17 is an XOR circuit, and the output of the first or second notification control means 4.6 is High.
A resistor 018 keeps the output high only during hO, and a transistor 19 amplifies the output of the XOR circuit 17 and drives the buzzer 2o.

Therefore, after the output A of the dryness detection means 2 becomes High, the buzzer 20 will sound intermittently for a certain period of time to notify that the clothes have been dried to the point where they are moist enough to be ironed, and further, After the output of the delay means 3 becomes Hi q h, the buzzer 2o continuously sounds for a certain period of time, notifying that the drying has progressed to a complete state. It is up to the user to decide in which state the drying operation should end, but the difference in tone allows the user to reliably and easily obtain the desired drying state.

As described above, the present invention detects the slightly damp state of the clothes to be dried, and by providing a means for distinguishing and notifying this, the clothes can be re-steamed when the clothes are to be ironed after being dried in the dryer. You can omit the wasteful work of moistening.
Moreover, it contributes to energy saving by shortening the operating time of the dryer.
